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. 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). * - Check each sub-task time counter to see if it has passed it's respective * threshold. No special libraries are required, so there is no need to download anything else. A message in the Serial Monitor stating that movement has ceased. Whats people lookup in this blog: I hope it is working well for you. The project uses a ATmega328P which is very common in the Arduino scene. £20.49 £ 20. Adding to your basket. Automatic Stair Lights. The system is fully automatic, as you enter your stairwell the lights will light your path. Generally you want them to be about in the middle. Check the Tx setting on your PIR. Stair light controller - Reactive Lighting - Stair Lighting System - Automatic LED Stair Lighting (the driver for lighting effects) version 11 to 14 s. Average rating (5/5): (votes 1) Availability: Availability - 3 days. faderTime = FADE_OFF_TIME; // Set the timer threshold that controls how frequently we decrease the brightness. Written by: Alan Parekh at 5:37 am. Written by: Alan Parekh at 5:37 am. Top Rated Seller Top Rated Seller. 2 months ago. how do you want the PIR's to affect the LED status. No wires = quick and easy installation in less than 5 minutes; no electrician required. Automatic staircase lighting is an option for staircases which do not need a constant illumination. Automatic lighting sequentially illuminates every step when going along the staircase at night. Mr. Beams Wireless Motion Sensor LED Light Step/Deck - Brown - 35 lumens - Multi-Purpose (37) $17. 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. Some 2N7000 mosfets are used to drive the actual LED lights. Insert your LDR and 10K resistor (Brown, Black, Black, Red) so that one of the LDR's leads is connected to the one of the resistor leads. * - If the PIR has changed state, initiate the appropriate action for the LED. If you enable debugging, the "light on threshold" will be automatically be adjusted to a much higher value. 1023 - 1023 = 0) int lightLevel = 1023 - analogRead(lightSensorPin); // Photo resistor with 10K voltage divider return lightLevel; }/************************************* * process Light check * sub task that periodically reports the current ambient light level. CAD $9.99. 1 year ago, could this be used on a set of outdoor stairs??? You cross one of the sensors and the steps on your ladder will start to turn on smoothly and alternately in front of you. getting dimmer)int brightness = 0; // The current brightness. If so, report the ambient light level. Select Options. the video above to see what a typical installation looks like and one of

"); } }}/************************************* * 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. So if you are all rugged up on a cold winter day, it might not trigger because all of the clothes you are wearing are keeping you warm. By adding a WiFi module, you can get it to report when the lights came on and/or when motion was detected. However, there might be a better way. LED Wireless Step Stair Auto Light PIR Motion Sensor Pathway Stair Wall Light . Also, I was a little bit worried about running the wire across the stairs to the other side as there is no "under stair" access for me to run the wire across under the stairs. }/************************************* * Fade Off * Initiates the turning OFF of the LED strip. A motion sensor activates the lights when you're within 16 inches, making them perfect for lining a stairway or hallway at night. The Anode (usually a red wire) connects to the positive voltage supply. You can add more than the examples show if you so desire, just be sure to update the pirPins array definition. )As for the duration, you could probably put in a timer - i.e. pirTopOfStairsState = valTop; pirBottomOfStairsState = valTop; if (pirTopOfStairsState == HIGH || pirBottomOfStairsState == HIGH) { // If either pir is activated (HIGH), then consider fadeingOn, otherwise, fade off.Please note that I do not have the bandwidth to test this anytime soon, so there may still be some other things that need attention, but that should be most of what is needed to add a second PIR sensor...Let me know how you went, and please click the "I made it too" button. * Ambient light sensor inhibits operation when not needed, * 8 Lighting sequence modes
Since the system has full individual lighting control for each step turning the lights on can be done is a number of exciting ways. pirReadTmr += delta; faderDelayTmr += delta; lightCheckTmr += delta; // Has the pir timer passed it's threshold? Optionally, for initial testing, you might consider not using the 12 volt supply. 98 / each. * - set up the MOSFET (ledStripPin) and builtin LED PIN to output * - Initialise the multi-tasking timer (timePrev), */void setup() { Serial.begin(9600); int cnt = 0; // Wait for the the Serial port to initialise (but don't wait forever) while (!Serial && cnt < 100) { cnt++; delay(10); } // Set the digital outputs (LED_BUILTIN and LED Strip MOSFET) pinMode(LED_BUILTIN, OUTPUT); digitalWrite(LED_BUILTIN, LOW); pinMode(ledStripPin, OUTPUT); Serial.println("Ready"); // Initialise the time Keeper timePrev = millis();}/***************************************************************************** * Loop: * - Check to see if the time has changed. 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. You can simply leave the 12 volt supply and MOSFET out of the circuit. 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). It would be wonderful if you click the "i made it" button above. One 3 pin header (for connecting the PIR). White Recessed Lighting Step Light Model# H2920ICT $ 26 06 $ 26 06. // Similarly as it get's brighter, the LDR's resistance get's closer to zero, therefore the voltage at A0 gets lower, // which is read as lower values at A0. SMART Home LED Lighting System and More . I needs to go on for 30 seconds and the off again.2. 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. Once-over or step-light is a potential place where LEDs are a better option than incandescent bulbs. So maybe in a later state when i understand it more i could ask it. because a PIR works by detecting movements of warm bodies. Note: You will need to modify the code (next step) to tell the program where you have connected the additional PIR modules. These can be applied directly under the stair, or embedded in a milled channel. The idea is to control two sensory infrared “beams”–a lower beam for the bottom step and another at the top of the stairs. That's fine i will try and find other solutions. I would suggest renaming some of the variables to have meaningful names (e.g. Nice project. https://www.instructables.com/id/Cooperative-Multi... A night light for a baby's room - LED under crib, PIR facing door. Reply if (pirReadTmr >= PIR_TIME) { processPir(); pirReadTmr = 0; } // Has the fader timer passed it's threshold? full brightness). * Automatic operation
As soon as-over or step-light is a possible place the place LEDs are a greater choice than incandescent bulbs. 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. Halo H29 9 in. Get it as soon as Tue, Jan 12. A center hole is... more info. On my PIR, there are two variable resistors on the back. 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. Similar projects you might like. S p M o n X F J s o r 3 e Y d P 1 V G 9. If the light level is above// this threshold, the LED strip will not be turned on when motion is triggered.#define LIGHT_ON_THRESHOLD 200// The pins to which the various peripherals are connected.int pirTopOfStairsPin = 2; // Input: The signal from the PIR.int pirBottomOfStairsPin = 4; // Input: The signal from the PIR.int ledStripPin = 3; // Output: PWM signal to the MOSFET.int lightSensorPin = A0; // Input: The reading from the ligh sensor (LDR)// Cooperative multi-tasking data.// Cooperative multi-tasking works by activating a task from time to time.// The period of time between activations depends upon the task.// This variables is used to track the point in time that we last checked the// Arduino clock. Once you get the project running, just replace the 470 ohm resistor + LED with the MOSFET + LED Strip. Once you've connected everything up, take a break, then double check your connections. 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. You should see: Wait for a while without moving. Find many great new & used options and get the best deals for Sensors for automatic LED Stair Lighting "SmartStairway SS-26" at the best online prices at eBay! The Tx is the time delay before the PIR reports that motion has ceased. Both worked just fine. “the stair butler”). I'm finding 5-10k, 15-100k... seems to vary. fadeUp = true; // Set the direction to "turn on LED's" (i.e. Check the datasheet for your MOSFET to determine which pin is the Gate. 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. Compare. Compare. This might happen * part way through the LED turning off cycle. The wire colours correspond to the wiring diagram shown above. 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. The Arduino's built in LED should turn off. The safety of the stairwell is enhanced when it's well lit. If you are nervous (like I was) about connecting the 12 Volt supply. A totally invisible light source, each tread is clearly defined yet the staircase appears to float and casts interesting shadows into the void below. For initial testing, you can remove the 12 volt light strip and MOSFET and simply connect a single LED with a 470 Ohm resistor between Pin 3 and Ground. * * Note. Reply pirPin to pirTopOfStairsPin and pirState to pirTopOfStairsState) then when you add the second variable you could also give it a meaningful name (e.g. Reactive Lighting : - Stair Lighting Systems LED Stair Lights Miscellaneous Custom Order stair, lighting, controller, led, automatic, low voltage, 12 volt, flush mount, surface mount, motion activated, safety, home automation, 3 way lighting The other controls how long the "motion detected" signal remains on after the motion has actually stopped. The step and stair light instantly turns on when it detects motion from up to 15-ft away. 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? RC Arduino Domino Layer With Bluetooth App Control, https://learn.adafruit.com/pir-passive-infrared-proximity-motion-sensor/how-pirs-work. A wide variety of automatic led stair lighting options are available to you, such as color temperature(cct), lamp body material, and item type. After a few seconds, you should see: Try turning on DEBUG mode by uncommenting the line "#define DEBUG" near the top of the program. Reply * A value of 127 means roughly 50% of the time ON and 50% of the time OFF (i.e. In this case, the LED might not always turn on when you expect it to as there is a lot of ambient light near the sensor - even though the stair well is dark. Let me know (and if possible post a photo) if you make it. Thanks for the feedback.I've also just posted another project which describes how to get Arduino to seemingly do multiple things at once.This project builds up from a simply blinking one LED with a push button that "controls it", to a Mega Blinky LED Extravaganza.It is all about the coding (but also makes a nice blinky light thingy). But thanks for the project and helping so far already.
