Its operation consists in slowly switching on the lighting of the entire stairs and after a set time, slowly switching off the lighting. If you do not use unsigned long, then // after a few days your multi-tasking might "freak out" (the technical term for // not performing as expected). * 16 independent stair outputs A message in the Serial Monitor stating that movement has been detected. My friend, and HacDC cohort, Erica Kane, put together this wonderful set of automated LED stair lights together after seeing this post on MAKE. on Step 5, Sure....I will also add it to the Instructable. You can reinvent even a modest space with the help of imaginative stair lights. The LED light strip is controlled via a MOSFET and features a rather cool "fade on" and "fade off" effect. the video above to see what a typical installation looks like and one of Then, "fadeOn" if either of the PIR's are on (HIGH) and fadeOff when both are off (LOW). digitalWrite(LED_BUILTIN, LOW); fadeOff(); // initiate the turn LED's off sub-task } }}/************************************* * Fade On * Initiates the turning ON of the LED strip. 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. 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. we are "fading" the LED's) if (fadeUp) { // Are we increasing the brightness? For now, the Arduino and senors simply sit on the floor up against the wall. 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. * The overall result is the that the LED's will smoothly transition from whatever brightness level * they happened to be at back to full brightness with no ugly blinking, flashing or sudden jump to * an extreme level of brightness. offers 967 automatic led stair lighting products. The proportion of time that the LED's are ON compared * to the time that they are off is directly related to the value written to the port (i.e. Mr. Beams Wireless Motion Sensor LED Light Step/Deck - Brown - 35 lumens - Multi-Purpose (37) $17. 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). The Anode (usually a red wire) connects to the positive voltage supply. If so, report the ambient light level. One 3 pin header (for connecting the PIR). 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 would suggest renaming some of the variables to have meaningful names (e.g. * - Check each sub-task time counter to see if it has passed it's respective * threshold. if (timeNow != timePrev) { // Yep, so work out how long has passed (normally 1 ms) unsigned int delta = timeNow - timePrev; // Capture the current time so we can check if time has moved on from "right now". I built a second copy of the electrical circuit on an Arduino prototyping shield. China Ip44 Led Automatic Induction Lamp Corridor Step Lights How to make automatic led stair lighting you how to make stair led lighting with motion sensors you automatic led stair lighting smartstairway tutorial automatic led stair lighting system smartstairway ss 26. Wireless automatic LED solar deck lights, please contact us with any product problem to assure your satisfaction SPECIFICATIONS Wattage: 0.12 watts Happy New Year/Free Shipping Over $29.98 Specify link list in Theme Settings > Header Automatic LED Stair Lighting. * A value of 0 means the LED's are ON for 0% of the time and OFF 100% of the time (i.e. Some double sided tape holds the PIR to a door frame. So I will add on to this project an option of a second PIR.2) Since you have already had a go at writing the code, might I suggest asking a question on stack overflow specifically the Arduino sub-site ( ?Anyway, apart from the power supply, it is operating on 12 Volts, so weather shouldn't be a problem.I would be inclined to seal it in a project box of some sort. One of them controls the sensitivity. The STX-1791 controller is used for static lighting control of stairs. Automatic illumination of a ladder This system is designed to organize a beautiful staircase lighting. timePrev = timeNow; // Update the sub-task time counters. the 12 volt parts connected to the MOSFET's source and drain). if (pirReadTmr >= PIR_TIME) { processPir(); pirReadTmr = 0; } // Has the fader timer passed it's threshold? 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. :-), Question By adding a WiFi module, you can get it to report when the lights came on and/or when motion was detected. Paradise Set of 2 solar LED accent lights with rectangular design and seeded glass lenses (23) $34. Our friend Edo who brought us the cool 64 RGB LED Table has just installed some stair lights into his stairwell. One N-Channel MOSFET. 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). "); } }}/************************************* * 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. The lights will also turn off automatically after the user entered time delay has completed. The other controls how long the "motion detected" signal remains on after the motion has actually stopped. I used a Leonardo, but any should work. LED stair lighting that you can adjust to any stair design will enable you to choose the color, brightness and size of the strips. 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). Now you can use as a pyroelectric infrared sensors and ultrasonic rangefinders, in any combination, as you need. That's fine i will try and find other solutions. I hope it is working well for you. In this case simply temporarily substitute the MOSFET and LED light strip with a single LED + 470 ohm resistor. */void processPir() { // Read the PIR and see if it's state has changed from last time we valTop = digitalRead(pirTopOfStairsState);int valBottom = digitalRead(pirBottomOfStairsState);if (valTop != pirTopOfStairsState || valBottom != pirBottomOfStairsState) { // Did either of the PIR's change state?pirTopOfStairsState = valTop;pirBottomOfStairsState = valTop;if (pirTopOfStairsState == HIGH || pirBottomOfStairsState == HIGH) { // If either pir is activated (HIGH), then consider fadeingOn, otherwise, fade off. Version 3.12. full brightness). 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. LEONLITE 120V Step Lights White Dimmable Indoor LED Stair Light, 150lm CRI 90, 3.5W 3000K Warm White, ETL Listed Outdoor Staircase, Aluminum Waterproof, 5-Year Warranty, Pack of 6 . Motion-activated "LIGHTDECOR" designed, LED Stair Lights. Our friend Edo who brought us the cool 64 RGB LED Table has just installed some stair lights into his stairwell. No special libraries are required, so there is no need to download anything else. I can change the duration of the ledstrip. }/************************************* * Fader sub-task * Adjusts the brightness of the LED strip. If you are nervous (like I was) about connecting the 12 Volt supply. That means no heat is escaping. In the long exposure picture above you can see what looks to be 4 lights per step but there is actually only 2, the other glowing spots is from the glossy varnish on the stairs reflecting the bright stair lights. Hook up your components by following the wiring diagram shown above and/or follow the instructions below. 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. 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. The controller is adapted to control the MONO LED strips arranged in stair steps or points (spots) LED … */void processLightCheck() { int lightLevel = getLightLevel(); Serial.print("Light level: "); Serial.println(lightLevel);}------------------------------------------------------------------------------------------------------------------------------------------------------------------------. */void fadeOn() { fadeDisabled = false; // Enable the fader sub-task. Once-over or step-light is a potential place where LEDs are a better option than incandescent bulbs. "get dimmer"). * Independent step lighting how do you want the PIR's to affect the LED status. Remember if you incorrectly connect any of the 12 Volt (VIN red wire) connections to the rest of the circuit you will probably release the "magic smoke" and that will be bad for your Arduino. Since the system has full individual lighting control for each step Ensure that the PIR is correctly connected (the Signal goes to PIN 2 on Arduino). * * Note. The photo shows my finished rig with the two sets of cables leading to the PIR and the LED strip. A message in the Serial Monitor stating that movement has ceased. 2 months ago. STX-1794 controller is used for dynamic lighting of the stairs. Free delivery with $45 order. I'm finding 5-10k, 15-100k... seems to vary. 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. LED Wireless Step Stair Auto Light PIR Motion Sensor Pathway Stair Wall Light . Additions in this version: 1 year ago. C $94.77 to C $164.69. "); } } else { // We are decreasing the brightness (turning the LED's off) if (brightness > 0) { // Is the current brightness more than the minimum possible value? Are you able to post it to a file sharing site (or better yet, github? 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. 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. By using the Arduino … Continue reading » Stair lighting with LED-strips. Finally, there is a light level sensor which is used to ensure that the LED's are turned on only when it is dark enough to warrant doing so. Mine is about 1.4m long and draws about 0.5A when turned on. 98 / each. Project in … I see no reason why it could not be used on a set of outdoor stairs. Our main loop will continually check to see if the Arduino's clock// has ticked over (> 1ms has passed since we last did anything). Disable it.// Serial.println("Fade off done. Therefore the reading at A0 gets closer to +5V which is read as higher values at A0. 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 :-)). or what would you need to weatherproof this setup for a northern climate. Create project and already build your project and this is working. If the light reading is less than the threshold, your LED strip (or test LED) should "fade on". That means you might not be detected by the PIR.Here is a quite good explanation of how they work (or do not work): 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. * Home Automation system compatible. The LED is only turned on if the ambient * light level is lower than a specified threshold. Also, I have described in the steps how to go about hooking up additional PIR(s). 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. 49 (£3.42/Item) Get it Friday, Jan 8. Question Once you get the project running, just replace the 470 ohm resistor + LED with the MOSFET + LED Strip. One LED light strip (not shown in the photo). If you fail to keep the 12V separate from the other pins, the "magic smoke" that makes electronic stuff work might escape.
