Since the system has full individual lighting control for each step * - If the time has changed, work out how long has elapsed since the last * time we checked (should always be 1 ms) * - Update the 3 sub-task time counters. The code still defines just a single PIR, but comments at line 37 show how to define more with examples for 2 and 3 PIRs. Brand New. The stairs are quite dangerous - especially at night - but not any more thanks to the Motion Activated Automatic LED Stair Lighting with Arduino (a.k.a. 1 year ago. By carefully positioning the LED’s and PIR sensor, this project could easily be adapted into: A night light for a baby’s room – LED under crib, PIR facing door. * Lighting system only operates when stairwell is in use This should be 12 volts or less as the Arduino will also be powered by the LED light strip's power supply through the Arduino's external power jack. */void loop() { // Get the current time in millis. In our case, the plastic tubing isn't to protect them from the weather. Sketch is very well commented, thanks for doing this. The Tx is the time delay before the PIR reports that motion has ceased. because a PIR works by detecting movements of warm bodies. Using KLUS’ new LED lighting extrusions, you can now place LED strips on any type of stairs. Due to the above, and at least one request, I've updated the code to support multiple PIR sensors. Nice project. Automatic LED Stair Lighting. Stairs lighting MONO Controller STX-1794 STX-1794 controller is used for dynamic lighting of the stairs. Testing is easiest if the Arduino is connected to your computer and you monitor the debug messages on the serial monitor in the Arduino IDE. If you enable debugging, the "light on threshold" will be automatically be adjusted to a much higher value. That means you might not be detected by the PIR.Here is a quite good explanation of how they work (or do not work): https://learn.adafruit.com/pir-passive-infrared-proximity-motion-sensor/how-pirs-workHaving said that if in your environment a PIR does not work for you, you could always try other triggering mechanisms such as breaking an Infrared light beam (at the approaches to the stairs), pressure plates, vibration sensors and so on. "the stair butler"). By using the Arduino … Continue reading » Automatic stair led lighting – LED lights are slowly changing most of our lights in properties, companies and public locations in addition to when it comes to their many benefits over conventional types of lighting. Remove the test LED and 470 ohm resistor. "get dimmer"). If you turn it the other way, the "motion detected" signal will stay on for much longer after the motion has stopped. A message in the Serial Monitor stating that movement has ceased. Whenever the beam detects something interrupts (like feet) then the stairs light up, and after a 15 second delay, the lights … Our motion sensor-activated, programmable stair lighting system lights up your stairs automatically when you enter the staircase area.The kit contains all that you need to have impressive stair lights: individual LED strips with protective casing, motion sensors, programmable controller and power supply for quick and convenient installation. Hi Mikeoo, I am not sure if you are still interested, but I've updated the code to support any number of PIRs (obviously at least one is required :-)). the video above to see what a typical installation looks like and one of Project in … A welcome home at night light - position LED's in the entry hall with sensor facing the door. Whats people lookup in this blog: Automatic stair led lighting – LED lights are slowly replacing most of our lights in homes, businesses and public places as well as in terms of their many advantages over traditional forms of lighting. I am also a contributor (unpaid) over there. Now you can use as a pyroelectric infrared sensors and ultrasonic rangefinders, in any combination, as you need. Automatic illumination of a ladder This system is designed to organize a beautiful staircase lighting. This is especially handy when checking on baby at night time and you do not want to turn on the room lights (or you are carrying baby). if (brightness < 255) { // Yep, is the current brightness less than the maximum possible value? Reply I'm assuming you mean something like Alaska??? Therefore the reading at A0 gets closer to +5V which is read as higher values at A0.

Since originally posting this, I have moved and no longer have the stairs, however, I have a poorly lit entrance/passageway, so this is a welcome addition to our new place. Try turning it to either extreme. It is possible that the PIR will report that "motion has stopped". Connect the other end of the resistor to Pin 3 on the Arduino (Green wire), Connect the MOSFET's drain (most likely the middle pin and heat sink) to the Cathode of the LED strip (blue wire), Connect the MOSFET's source (right pin when holding the MOSFET as described above) to GND (black wire), Connect the Anode of the LED Strip to the 12V rail (red wire). Hampton Bay LED Deck and Stair Lights 8-Piece Kit (32) $74. That is checking the PIR state changes while simultaneously adjusting the * LED brightness (and as it happens, simultaneously reporting the ambient brightness once every second). I can change the duration of the ledstrip. fadeUp = false; // Set the direction to "turn off LED's" (i.e. Looks good.Stairs are pretty dangerous if not well lit and the older you get, the more likely you'll have a slip.Anything that saves messing about trying to find the light switch is a bonus. Refine Use the commented out code examples to show how 2 or 3 PIR modules are defined. The PIR is very sensitive to the slightest motion even at quite long distances.

I've never had anyone do that before!Anyway, to your question, basically you would mirror the existing pir code. That means no (or not much) IR. Automatic lighting system for steps of the ladder "SmartStairway SS-26" The new model is a set of automatic LED backlight stairs allows you to connect up to 26 steps of stairs. So maybe in a later state when i understand it more i could ask it. 49 (£3.42/Item) Get it Friday, Jan 8. getting dimmer)int brightness = 0; // The current brightness. But i liked to add a second PIR so i could use in for my stairs. do nothing). Halo H29 9 in. LED Wireless Step Stair Auto Light PIR Motion Sensor Pathway Stair Wall Light . The safety of the stairwell is enhanced when it's well lit. Our quality LED is so efficient, you will get more than 50 hours of light on one set of batteries. Since the system has full individual lighting control for each step turning the lights on can be done is a number of exciting ways. One Arduino. faderTime = FADE_OFF_TIME; // Set the timer threshold that controls how frequently we decrease the brightness. Free delivery with $45 order. Automatic Led Stairs Controller: ... no matter what LED lights I use - RGB or regular. The backlight is switched on with the subsequent steps, depending on the motion directions: ascending or descending. This works on all surfaces - wood, stone, carpet, etc - and the effect can be modified by adjusting their height. In my case, there was a single wooden rail. Filed under Complex Hacks, Cool Gadgets, Electronic Hacks. The stair I hope it is working well for you. Simply connect the signal (or out) ports on the additional PIR modules to unused DIO pins on the Arduino. Our main loop will continually check to see if the Arduino's clock// has ticked over (> 1ms has passed since we last did anything). Apart from the power connections, there are three main parts to the circuit: Important note: The LED strip is powered from a 12V power source. This will be extracted from the VIN pin on the Arduino. The PIR is facing down into the stair well and detects motion both at the top of the stairs and the bottom. If so, adjust the brightness of the LED's if (faderDelayTmr >= faderTime) { processFade(); faderDelayTmr = 0; } // Has the ambient light level timer passed it's threshold? If you saw the messages and the builtin LED turn on / off but the LED strip (or test LED) did not light, then: Tip: You can artificially lower the ambient light levels by covering the LDR with your fingers or a piece of card. if (pirReadTmr >= PIR_TIME) { processPir(); pirReadTmr = 0; } // Has the fader timer passed it's threshold? Serial.println("Motion Detected"); // Yep! I expect the dome on the PIR would protect it, you could probably put the LDR behind some transparent plastic etc.As the the LED's, I do not know how harsh your climate is, but I have seen outdoor LED's that come in plastic tubing. )As for the duration, you could probably put in a timer - i.e. true = ON (i.e. * User selectable on time delay I used my test rig and a print statement to narrow in on the A0 reading that corresponded to a good level of light to trigger the Fade On.So put another way, it probably doesn't matter (within reason) a huge amount what the LDR and 10K resistor values are - just as long as you get usable values at A0.I hope this helps. These can be applied directly under the stair, or embedded in a milled channel. Note: If you are using more than 1 PIR, you will need to modify the definition of the pirPins array (about line 37) in the following code. totally off). Compare. Light starts with motion… We design and implement automatic LED lighting systems for stairs, furniture and other structures.. Automatic stair lighting with motion sensors is a finding of modern electric engineering which allows the owners of multi-layer apartments and country houses possess the “smart” lighting actuating at the moment of motion along the staircase. Connect the point where the LDR and resistor are connected to A0 on the arduino (grey wire), Connect the other end of the LDR to the ground rail, Connect the other end of the 10K resistor to the 5V rail (orange wire), Connect the Power pin on the PIR to the 5V rail on the breadboard (Orange wire), Connect the Ground pin on the PIR to the GND rail on the breadboard (Black wire), Connect the Signal pin on the PIR to pin 2 (D2) on the Arduino (yellow wire). Automatic LED Stair Lighting. Did you make this project? Both worked just fine. as a "safety light" in a babies room (LED strip under baby's bed) so that illuminates when parents have to check on baby in the middle of the night.Having the LED strip under the bed means that there isn't a bright light shining directly into baby's or parent eyes as would potentially be the case from a room light or a bedside lamp.Also, the brightness can be controlled by "capping" the PWM at say 50% illumination to get the level of light just right. Its operation consists in slowly switching on the lighting of the entire stairs and after a set time, slowly switching off the lighting. The LED strip is quite bright. * A value of 255 means 100% of the time ON and 0% of the time OFF (i.e. Once you've connected everything up, take a break, then double check your connections. A wide variety of automatic led stair lighting options are available to you, such as color temperature(cct), lamp body material, and item type. White Recessed Lighting Step Light Model# H2920ICT $ 26 06 $ 26 06. Connection is not the problem but adding it to the code.Any tips how to add the second PIR to the code. Stair lighting with LED-strips One way to illuminate a stairway is the use of LED strips. the 12 volt parts connected to the MOSFET's source and drain). Edo has started a new Youtube account which will contain all of his interactive furniture creations. The controller is adapted to control the MONO LED strips arranged in stair steps or points (spots) LED … When i cover the light sensor ledstrip goes on but stays on.When i checked serial monitor i keeps showing: Motion Detected -- Motion ended -- Motion Detected --Motion ended etc etc.Sometimes i show the lux value and brightness level.So i think it needs to have some more tweaking but need to order 2 PIR for it because it is not easy to test it with the live project and much easier to test it first and when it is working i test it with the stairs.I will let you know how it goes and if you have some though about it let me know.p.s can you tell me how 1. Following is the entire program. * Note that the brightness of the LED's is written to the LED strip PIN using analogWrite. If this occurs, then the fadeOFf will immediately be * stopped and the fadeOn will be initiated. Try adjusting the sensitivity. Note: LED light strips are typically 12 volt. Optionaly an aluminumprofile can be used, which protects the strip against damage and diffuses the light optimally. CAD $9.99. Optionaly an aluminumprofile can be used, which protects the strip against damage and diffuses the light optimally. turning the lights on can be done is a number of exciting ways. 1 year ago The Arduino source can also be obtained from GitHub account at: If you wish to make a more permanent setup, then I would recommend getting a second set of parts 1 through 7 from the above list - plus: It is not strictly necessary to get the second set of parts, but in my circumstance I find it easier to have two setups of the project. I have one which claims that it will remain on for (I think) 30 minutes after motion has ceased (it is an outdoor security light+sensor). We built it using addressable LEDs, motion sensors and we custom programmed an… LED automatic stair lights… LED Motion Sensor Lights Indoor -170 LED Closet Light Bright with 3 Color Modes Rechargeable Cupboard Light Dimmable Under Cabinet Lighting Wardrobe Light for Cupboard, Wardrobe, Stair, Kitchen 4.4 out of 5 stars 26 As soon as-over or step-light is a possible place the place LEDs are a greater choice than incandescent bulbs. Get it as soon as Tue, Jan 12. or what would you need to weatherproof this setup for a northern climate. You must be careful to never connect the 12V power source to any of the other Arduino pins. if (lightCheckTmr >= LIGHT_CHECK_TIME) { processLightCheck(); lightCheckTmr = 0; } }}/***************************************************************************** * Multi-tasking sub tasks start here */ // Variable to track the last known state of the PIR - initially this should be OFF.int pirTopOfStairsState = LOW;int pirBottomOfStairsState = LOW;// Variables to track what the LED control is doing.bool fadeDisabled = true; // Are we fading? If you fail to keep the 12V separate from the other pins, the "magic smoke" that makes electronic stuff work might escape. The project uses a ATmega328P which is very common in the Arduino scene. pirReadTmr += delta; faderDelayTmr += delta; lightCheckTmr += delta; // Has the pir timer passed it's threshold? In this case simply temporarily substitute the MOSFET and LED light strip with a single LED + 470 ohm resistor. 1023 - 0 = 1023) // darker ambient light (high reading) gives lower result (e.g. If nothing seems to have happened (no motion detected/ceased messages): You see motion detected message, but never see the motion ceased message: If you have used a single test LED (i.e. Stairs led lighting - the intelligent controller for universal stair steps 11-14 Intelligent controller to the stairs - a fantastic effect by energy-efficient LED lighting Specifications: - Number of output lighting: 11-14 - Output voltage 12V, Features and advantages of the controller: - Control of 11-14 strps. */void fadeOn() { fadeDisabled = false; // Enable the fader sub-task. The easiest way would be to not modify the loop per se, but modify the function it calls (processPir).The trickiest bit will be to implement the logic that you want - i.e. In the end I simply stuck some double sided (1mm thick) tape to the hand rail and my LED strip to the double sided tape. Sınırlı Automatic Led Stair Lighting fırsatlarını kaçırmayın! I built this Arduino based automatic LED light controller for a set of poorly lit stairs in our new home. Assembled $39.00 Note when mounting the LDR, ensure it is facing into your stair well.

Smart lighting controller for stairs and hallways full kit available to buy Paradise Set of 2 solar LED accent lights with rectangular design and seeded glass lenses (23) $34. On my PIR, there are two screw variable resistors labelled Sx and Tx. If you are nervous (like I was) about connecting the 12 Volt supply. @mikeoo, unfortunately I have not been able to look at your code and probably won't be able to do so anytime soon. View cart for details. note that the pirPin variable appears in two places in the code and the pirState variable appears 4 times. It is programmable to any user-defined light intervals and sequences. "get brighter"). Mine is about 1.4m long and draws about 0.5A when turned on. * * An LDR (Analog A0) is used to detect ambient light levels. This might happen * part way through the LED turning off cycle. It is unfortunate that code does not format well in the comments section. I also tried IRF540N. That's fine i will try and find other solutions. 99. Ensure that the PIR is correctly connected (the Signal goes to PIN 2 on Arduino). If you turn it completely to one end, it will turn the "motion detected" signal off pretty much as soon as the motion actually stops. Automatic lighting system for steps of the ladder "SmartStairway SS-26" The new model is a set of automatic LED backlight stairs allows you to connect up to 26 steps of stairs. This allows me to to manage fading the LED's on and off while simultaneously detecting movement via the PIR motion detector and reporting light levels. * * While the above scenario can be handled without multi-tasking, it is much easier (IMHO) to do with * this form of multi-tasking. The photo shows my finished rig with the two sets of cables leading to the PIR and the LED strip. brightness++; // Yep, increase the brightness and write it to the ledStripPin analogWrite(ledStripPin, brightness); } else { fadeDisabled = true; // We have reached the maximum brightness (=255) so this task is done. Mine worked best when it was set in the middle. The LED light strip is controlled via a MOSFET and features a rather cool "fade on" and "fade off" effect. pirBottomOfStairsPin and pirBottomOfStairsState) or whatever names are meaningful to you. Thanks for the help love working with Arduino but i just started so still searching and trying a lot.I have done the I made it too part because you earned it of course...Tried the code and made some changes (typo) but it is not working. Initially the LED's are off, therefore the brightness is 0./************************************* * Process PIR * - Called when it is time to check the PIR to see if it has changed state. On my PIR, there are two variable resistors on the back. A totally invisible light source, each tread is clearly defined yet the staircase appears to float and casts interesting shadows into the void below.

I built a second copy of the electrical circuit on an Arduino prototyping shield. 99 RC Arduino Domino Layer With Bluetooth App Control, https://learn.adafruit.com/pir-passive-infrared-proximity-motion-sensor/how-pirs-work. The PIR motion detector(s) (Pin 2 on Arduino and additional pins as needed), The LDR light level sensor (Pin A0 on Arduino), 12V supply (VIN) to one of the power rails on your breadboard (red wire), Ground (GND) to one of the ground rails on your breadboard (black wire), Connect both of the ground rails on your breadboard together (black wire). Since originally posting this, I have moved and no longer have the stairs, however, I have a poorly lit entrance/passageway, so this is a welcome addition to our new place. This along with a second Arduino was installed near the approach to the top of the stairs. Ensure that the reported ambient light levels are less than the threshold set in the Arduino program's constant: LIGHT_ON_THRESHOLD. LED's turn on automatically when you open the front door. As soon as-over or step-light is a possible place the place LEDs are a greater choice than incandescent bulbs. The step and stair light instantly turns on when it detects motion from up to 15-ft away. When it detects someone approaching, the LED light strip is turned on. Make sure you (and anyone else nearby - including your cat if you have one) are perfectly still (try covering the PIR) while waiting for motion detection to cease. when I saw your photo, I was reminded that my sister has the same type of stair case. From China +C $3.29 shipping. Adding to your basket. Disable it.// Serial.println("Fade off done. This DIY Strip Light Stair Lighting Design and Install over at Speedy Signals looks nice.

Since the system has full individual lighting control for each step * - If the time has changed, work out how long has elapsed since the last * time we checked (should always be 1 ms) * - Update the 3 sub-task time counters. The code still defines just a single PIR, but comments at line 37 show how to define more with examples for 2 and 3 PIRs. Brand New. The stairs are quite dangerous - especially at night - but not any more thanks to the Motion Activated Automatic LED Stair Lighting with Arduino (a.k.a. 1 year ago. By carefully positioning the LED’s and PIR sensor, this project could easily be adapted into: A night light for a baby’s room – LED under crib, PIR facing door. * Lighting system only operates when stairwell is in use This should be 12 volts or less as the Arduino will also be powered by the LED light strip's power supply through the Arduino's external power jack. */void loop() { // Get the current time in millis. In our case, the plastic tubing isn't to protect them from the weather. Sketch is very well commented, thanks for doing this. The Tx is the time delay before the PIR reports that motion has ceased. because a PIR works by detecting movements of warm bodies. Using KLUS’ new LED lighting extrusions, you can now place LED strips on any type of stairs. Due to the above, and at least one request, I've updated the code to support multiple PIR sensors. Nice project. Automatic LED Stair Lighting. Stairs lighting MONO Controller STX-1794 STX-1794 controller is used for dynamic lighting of the stairs. Testing is easiest if the Arduino is connected to your computer and you monitor the debug messages on the serial monitor in the Arduino IDE. If you enable debugging, the "light on threshold" will be automatically be adjusted to a much higher value. That means you might not be detected by the PIR.Here is a quite good explanation of how they work (or do not work): https://learn.adafruit.com/pir-passive-infrared-proximity-motion-sensor/how-pirs-workHaving said that if in your environment a PIR does not work for you, you could always try other triggering mechanisms such as breaking an Infrared light beam (at the approaches to the stairs), pressure plates, vibration sensors and so on. "the stair butler"). By using the Arduino … Continue reading » Automatic stair led lighting – LED lights are slowly changing most of our lights in properties, companies and public locations in addition to when it comes to their many benefits over conventional types of lighting. Remove the test LED and 470 ohm resistor. "get dimmer"). If you turn it the other way, the "motion detected" signal will stay on for much longer after the motion has stopped. A message in the Serial Monitor stating that movement has ceased. Whenever the beam detects something interrupts (like feet) then the stairs light up, and after a 15 second delay, the lights … Our motion sensor-activated, programmable stair lighting system lights up your stairs automatically when you enter the staircase area.The kit contains all that you need to have impressive stair lights: individual LED strips with protective casing, motion sensors, programmable controller and power supply for quick and convenient installation. Hi Mikeoo, I am not sure if you are still interested, but I've updated the code to support any number of PIRs (obviously at least one is required :-)). the video above to see what a typical installation looks like and one of Project in … A welcome home at night light - position LED's in the entry hall with sensor facing the door. Whats people lookup in this blog: Automatic stair led lighting – LED lights are slowly replacing most of our lights in homes, businesses and public places as well as in terms of their many advantages over traditional forms of lighting. I am also a contributor (unpaid) over there. Now you can use as a pyroelectric infrared sensors and ultrasonic rangefinders, in any combination, as you need. Automatic illumination of a ladder This system is designed to organize a beautiful staircase lighting. This is especially handy when checking on baby at night time and you do not want to turn on the room lights (or you are carrying baby). if (brightness < 255) { // Yep, is the current brightness less than the maximum possible value? Reply I'm assuming you mean something like Alaska??? Therefore the reading at A0 gets closer to +5V which is read as higher values at A0. Upgraded Solar Stair Lights, Environmental Friendly Step Lighting Waterproof LED Light Dark Sensing Auto On/Off Deck Lights for Dock Pier Deck Pack of 8 with 3 LED 4.2 out of 5 stars 12 CDN$ 50.68CDN$50.68 Get it by Sunday, Dec 20 The Anode (usually a red wire) connects to the positive voltage supply. */void processFade() { // First, check to see if the sub-task is active? Since originally posting this, I have moved and no longer have the stairs, however, I have a poorly lit entrance/passageway, so this is a welcome addition to our new place. Try turning it to either extreme. It is possible that the PIR will report that "motion has stopped". Connect the other end of the resistor to Pin 3 on the Arduino (Green wire), Connect the MOSFET's drain (most likely the middle pin and heat sink) to the Cathode of the LED strip (blue wire), Connect the MOSFET's source (right pin when holding the MOSFET as described above) to GND (black wire), Connect the Anode of the LED Strip to the 12V rail (red wire). Hampton Bay LED Deck and Stair Lights 8-Piece Kit (32) $74. That is checking the PIR state changes while simultaneously adjusting the * LED brightness (and as it happens, simultaneously reporting the ambient brightness once every second). I can change the duration of the ledstrip. fadeUp = false; // Set the direction to "turn off LED's" (i.e. Looks good.Stairs are pretty dangerous if not well lit and the older you get, the more likely you'll have a slip.Anything that saves messing about trying to find the light switch is a bonus. Refine Use the commented out code examples to show how 2 or 3 PIR modules are defined. The PIR is very sensitive to the slightest motion even at quite long distances. [6 Pack ] Criacr Motion Sensor Light, Battery Powered Under Cupboard Night Light with Adhesive Pads and Magnet, 6 LED Wardrobe Night Lights for Stair, Cupboard, Cabinet, Kitchen (White) 4.5 out of 5 stars 766. LED stair lighting that you can adjust to any stair design will enable you to choose the color, brightness and size of the strips. 98 / each. * * Each time this sub-task is called, it will increase (or decrease) the brightness by 1 if the sub-task is enabled. If so, report the ambient light level. The Arduino will not be able to supply enough power (voltage or current) directly to turn on an LED light strip. The changes are relatively minor and I will briefly describe them below. One LED light strip (not shown in the photo). One 1 AMP 12-V DC power supply with a 2.1mm Barrel jack suitable to plug into your Arduino. If your "magic smoke" escapes, your Arduino probably will not work anymore and may even damage your computer if it is connected via USB. But thanks for the project and helping so far already. Additionally, we plan to install this into our parents home as a sort of night light for bathroom trips in the middle of the night. 10/20 x LED Deck Stair Light Waterproof Yard Garden Pathway Patio Landscape Lamp. Whenever the beam detects something interrupts (like feet) then the stairs light up, and after a 15 second delay, the lights … Written by: Alan Parekh at 5:37 am. LED lights are very convenient, because with the help of the remote control you can adjust the light intensity, and even color. No wiring or hardware is needed to install them they come with double-sided adhesive so you can affix them almost anywhere. "); } } else { // We are decreasing the brightness (turning the LED's off) if (brightness > 0) { // Is the current brightness more than the minimum possible value? "); } }}/************************************* * get Light Level * Check and return the ambient light level in a range from 0 (darkest) to 1023 (brightese) */int getLightLevel() { // Calculate the light level as the inverse of the value read. }/************************************* * Fade Off * Initiates the turning OFF of the LED strip. Hook up your components by following the wiring diagram shown above and/or follow the instructions below. Connect the Gate Pin to the 470 ohm resistor. The system is designed to be used in conjunction with LED lights or LED stripes with a voltage of 12 or 24 VDC. Share it with us! true = NO, false = YESbool fadeUp = true; // Which direction are we fading? Price:90.00 USD. Instead, simply connect a single LED and 470 ohm resistor between PIN 3 and ground. :-). One of them controls the sensitivity. Some double sided tape holds the PIR to a door frame. Version 3.12. Top Rated Seller Top Rated Seller. The wire colours correspond to the wiring diagram shown above. By adding a WiFi module, you can get it to report when the lights came on and/or when motion was detected. getting brighter), false = OFF (i.e. Stair lights, stair lighting, profil led automatic staircase light, aluminium profile, aluminium channel, LED power supplies, stair lamps, RGBW controllers, LED bulbs, LED halogen lamps sensors and electrical appliances will ensure high quality Lighting, durability and reliability, regardless of … My friend, and HacDC cohort, Erica Kane, put together this wonderful set of automated LED stair lights together after seeing this post on MAKE. $79.99 $ 79. I've never had anyone do that before!Anyway, to your question, basically you would mirror the existing pir code. That means no (or not much) IR. Automatic lighting system for steps of the ladder "SmartStairway SS-26" The new model is a set of automatic LED backlight stairs allows you to connect up to 26 steps of stairs. So maybe in a later state when i understand it more i could ask it. 49 (£3.42/Item) Get it Friday, Jan 8. getting dimmer)int brightness = 0; // The current brightness. But i liked to add a second PIR so i could use in for my stairs. do nothing). Halo H29 9 in. LED Wireless Step Stair Auto Light PIR Motion Sensor Pathway Stair Wall Light . The safety of the stairwell is enhanced when it's well lit. Our quality LED is so efficient, you will get more than 50 hours of light on one set of batteries. Since the system has full individual lighting control for each step turning the lights on can be done is a number of exciting ways. One Arduino. faderTime = FADE_OFF_TIME; // Set the timer threshold that controls how frequently we decrease the brightness. Free delivery with $45 order. Automatic Led Stairs Controller: ... no matter what LED lights I use - RGB or regular. The backlight is switched on with the subsequent steps, depending on the motion directions: ascending or descending. This works on all surfaces - wood, stone, carpet, etc - and the effect can be modified by adjusting their height. In my case, there was a single wooden rail. Filed under Complex Hacks, Cool Gadgets, Electronic Hacks. The stair I hope it is working well for you. Simply connect the signal (or out) ports on the additional PIR modules to unused DIO pins on the Arduino. Our main loop will continually check to see if the Arduino's clock// has ticked over (> 1ms has passed since we last did anything). Apart from the power connections, there are three main parts to the circuit: Important note: The LED strip is powered from a 12V power source. This will be extracted from the VIN pin on the Arduino. The PIR is facing down into the stair well and detects motion both at the top of the stairs and the bottom. If so, adjust the brightness of the LED's if (faderDelayTmr >= faderTime) { processFade(); faderDelayTmr = 0; } // Has the ambient light level timer passed it's threshold? If you saw the messages and the builtin LED turn on / off but the LED strip (or test LED) did not light, then: Tip: You can artificially lower the ambient light levels by covering the LDR with your fingers or a piece of card. if (pirReadTmr >= PIR_TIME) { processPir(); pirReadTmr = 0; } // Has the fader timer passed it's threshold? Serial.println("Motion Detected"); // Yep! I expect the dome on the PIR would protect it, you could probably put the LDR behind some transparent plastic etc.As the the LED's, I do not know how harsh your climate is, but I have seen outdoor LED's that come in plastic tubing. )As for the duration, you could probably put in a timer - i.e. true = ON (i.e. * User selectable on time delay I used my test rig and a print statement to narrow in on the A0 reading that corresponded to a good level of light to trigger the Fade On.So put another way, it probably doesn't matter (within reason) a huge amount what the LDR and 10K resistor values are - just as long as you get usable values at A0.I hope this helps. These can be applied directly under the stair, or embedded in a milled channel. Note: If you are using more than 1 PIR, you will need to modify the definition of the pirPins array (about line 37) in the following code. totally off). Compare. Light starts with motion… We design and implement automatic LED lighting systems for stairs, furniture and other structures.. Automatic stair lighting with motion sensors is a finding of modern electric engineering which allows the owners of multi-layer apartments and country houses possess the “smart” lighting actuating at the moment of motion along the staircase. Connect the point where the LDR and resistor are connected to A0 on the arduino (grey wire), Connect the other end of the LDR to the ground rail, Connect the other end of the 10K resistor to the 5V rail (orange wire), Connect the Power pin on the PIR to the 5V rail on the breadboard (Orange wire), Connect the Ground pin on the PIR to the GND rail on the breadboard (Black wire), Connect the Signal pin on the PIR to pin 2 (D2) on the Arduino (yellow wire). Automatic LED Stair Lighting. Did you make this project? Both worked just fine. as a "safety light" in a babies room (LED strip under baby's bed) so that illuminates when parents have to check on baby in the middle of the night.Having the LED strip under the bed means that there isn't a bright light shining directly into baby's or parent eyes as would potentially be the case from a room light or a bedside lamp.Also, the brightness can be controlled by "capping" the PWM at say 50% illumination to get the level of light just right. Its operation consists in slowly switching on the lighting of the entire stairs and after a set time, slowly switching off the lighting. The LED strip is quite bright. * A value of 255 means 100% of the time ON and 0% of the time OFF (i.e. Once you've connected everything up, take a break, then double check your connections. A wide variety of automatic led stair lighting options are available to you, such as color temperature(cct), lamp body material, and item type. White Recessed Lighting Step Light Model# H2920ICT $ 26 06 $ 26 06. Connection is not the problem but adding it to the code.Any tips how to add the second PIR to the code. Stair lighting with LED-strips One way to illuminate a stairway is the use of LED strips. the 12 volt parts connected to the MOSFET's source and drain). Edo has started a new Youtube account which will contain all of his interactive furniture creations. The controller is adapted to control the MONO LED strips arranged in stair steps or points (spots) LED … When i cover the light sensor ledstrip goes on but stays on.When i checked serial monitor i keeps showing: Motion Detected -- Motion ended -- Motion Detected --Motion ended etc etc.Sometimes i show the lux value and brightness level.So i think it needs to have some more tweaking but need to order 2 PIR for it because it is not easy to test it with the live project and much easier to test it first and when it is working i test it with the stairs.I will let you know how it goes and if you have some though about it let me know.p.s can you tell me how 1. Following is the entire program. * Note that the brightness of the LED's is written to the LED strip PIN using analogWrite. If this occurs, then the fadeOFf will immediately be * stopped and the fadeOn will be initiated. Try adjusting the sensitivity. Note: LED light strips are typically 12 volt. Optionaly an aluminumprofile can be used, which protects the strip against damage and diffuses the light optimally. CAD $9.99. Optionaly an aluminumprofile can be used, which protects the strip against damage and diffuses the light optimally. turning the lights on can be done is a number of exciting ways. 1 year ago The Arduino source can also be obtained from GitHub account at: If you wish to make a more permanent setup, then I would recommend getting a second set of parts 1 through 7 from the above list - plus: It is not strictly necessary to get the second set of parts, but in my circumstance I find it easier to have two setups of the project. I have one which claims that it will remain on for (I think) 30 minutes after motion has ceased (it is an outdoor security light+sensor). We built it using addressable LEDs, motion sensors and we custom programmed an… LED automatic stair lights… LED Motion Sensor Lights Indoor -170 LED Closet Light Bright with 3 Color Modes Rechargeable Cupboard Light Dimmable Under Cabinet Lighting Wardrobe Light for Cupboard, Wardrobe, Stair, Kitchen 4.4 out of 5 stars 26 As soon as-over or step-light is a possible place the place LEDs are a greater choice than incandescent bulbs. Get it as soon as Tue, Jan 12. or what would you need to weatherproof this setup for a northern climate. You must be careful to never connect the 12V power source to any of the other Arduino pins. if (lightCheckTmr >= LIGHT_CHECK_TIME) { processLightCheck(); lightCheckTmr = 0; } }}/***************************************************************************** * Multi-tasking sub tasks start here */ // Variable to track the last known state of the PIR - initially this should be OFF.int pirTopOfStairsState = LOW;int pirBottomOfStairsState = LOW;// Variables to track what the LED control is doing.bool fadeDisabled = true; // Are we fading? If you fail to keep the 12V separate from the other pins, the "magic smoke" that makes electronic stuff work might escape. The project uses a ATmega328P which is very common in the Arduino scene. pirReadTmr += delta; faderDelayTmr += delta; lightCheckTmr += delta; // Has the pir timer passed it's threshold? In this case simply temporarily substitute the MOSFET and LED light strip with a single LED + 470 ohm resistor. 1023 - 0 = 1023) // darker ambient light (high reading) gives lower result (e.g. If nothing seems to have happened (no motion detected/ceased messages): You see motion detected message, but never see the motion ceased message: If you have used a single test LED (i.e. Stairs led lighting - the intelligent controller for universal stair steps 11-14 Intelligent controller to the stairs - a fantastic effect by energy-efficient LED lighting Specifications: - Number of output lighting: 11-14 - Output voltage 12V, Features and advantages of the controller: - Control of 11-14 strps. */void fadeOn() { fadeDisabled = false; // Enable the fader sub-task. The easiest way would be to not modify the loop per se, but modify the function it calls (processPir).The trickiest bit will be to implement the logic that you want - i.e. In the end I simply stuck some double sided (1mm thick) tape to the hand rail and my LED strip to the double sided tape. Sınırlı Automatic Led Stair Lighting fırsatlarını kaçırmayın! I built this Arduino based automatic LED light controller for a set of poorly lit stairs in our new home. Assembled $39.00 Note when mounting the LDR, ensure it is facing into your stair well. One LDR (Light Detecting Resistor) photo detector, One 10K Resistor (Brown, Black, Black, Red, and any other colour), One 470 Ohm Resistor (Yellow, Violet, Black, Black and any other colour), One 2 way screw terminal block (for connecting the LED strip). I see no reason why it could not be used on a set of outdoor stairs. Version 3.12. Are you able to post it to a file sharing site (or better yet, github? Let me know (and if possible post a photo) if you make it. digitalWrite(LED_BUILTIN, HIGH); // Determine if we need to turn on the LED Strip. For now, the Arduino and senors simply sit on the floor up against the wall. These one foot White LED Strip Light can be mounted under the nose of your stairs for a hidden lighting look. Smart lighting controller for stairs and hallways full kit available to buy Paradise Set of 2 solar LED accent lights with rectangular design and seeded glass lenses (23) $34. On my PIR, there are two screw variable resistors labelled Sx and Tx. If you are nervous (like I was) about connecting the 12 Volt supply. @mikeoo, unfortunately I have not been able to look at your code and probably won't be able to do so anytime soon. View cart for details. note that the pirPin variable appears in two places in the code and the pirState variable appears 4 times. It is programmable to any user-defined light intervals and sequences. "get brighter"). Mine is about 1.4m long and draws about 0.5A when turned on. * * An LDR (Analog A0) is used to detect ambient light levels. This might happen * part way through the LED turning off cycle. It is unfortunate that code does not format well in the comments section. I also tried IRF540N. That's fine i will try and find other solutions. 99. Ensure that the PIR is correctly connected (the Signal goes to PIN 2 on Arduino). If you turn it completely to one end, it will turn the "motion detected" signal off pretty much as soon as the motion actually stops. Automatic lighting system for steps of the ladder "SmartStairway SS-26" The new model is a set of automatic LED backlight stairs allows you to connect up to 26 steps of stairs. This allows me to to manage fading the LED's on and off while simultaneously detecting movement via the PIR motion detector and reporting light levels. * * While the above scenario can be handled without multi-tasking, it is much easier (IMHO) to do with * this form of multi-tasking. The photo shows my finished rig with the two sets of cables leading to the PIR and the LED strip. brightness++; // Yep, increase the brightness and write it to the ledStripPin analogWrite(ledStripPin, brightness); } else { fadeDisabled = true; // We have reached the maximum brightness (=255) so this task is done. Mine worked best when it was set in the middle. The LED light strip is controlled via a MOSFET and features a rather cool "fade on" and "fade off" effect. pirBottomOfStairsPin and pirBottomOfStairsState) or whatever names are meaningful to you. Thanks for the help love working with Arduino but i just started so still searching and trying a lot.I have done the I made it too part because you earned it of course...Tried the code and made some changes (typo) but it is not working. Initially the LED's are off, therefore the brightness is 0./************************************* * Process PIR * - Called when it is time to check the PIR to see if it has changed state. On my PIR, there are two variable resistors on the back. A totally invisible light source, each tread is clearly defined yet the staircase appears to float and casts interesting shadows into the void below.
