Request for help: LED Control module for and 5050smd strip
-
I am looking for some help with a problem I’ve been trying to wrap my head around for about 4 month now. I have a 5m length of analogue LED strip (smd5050) that I want to attach surrounding my mirror providing lighting for the missus to be able to do her makeup etc. I have already prepped a circuit board using mosfets to control the strip as done in this tutorial https://dordnung.de/raspberrypi-ledstrip/. I’m however stuck on the software side, I haven’t done much JavaScript in some time and even then my knowledge was very basic. I’m looking to create a module with a) a button for on and off, b) a timer that can be set in config to auto turn off light if left on c) three vertical sliders to control the individual rub values of the strip. I know it’s pretty specific, I’m looking for some direction on how to achieve these things especially in regards to the sliders. Thanks in advance.

Hey mate,
here u can see my result: https://forum.magicmirror.builders/topic/6048/my-first-mirror-until-now/2
i used this tutorial: https://dordnung.de/raspberrypi-ledstrip/
its not a module for MM. But you can use Pigpio with an external script.
Just use the PIR or a button to turn on and off the lights.in my case the PIR starts a script where it turns on the monitor and turn on the mosfets slowly.
For the PIR i used this:
#!/usr/bin/env python import sys import time import RPi.GPIO as io import subprocess import pigpio io.setmode(io.BCM) SHUTOFF_DELAY = 119 # seconds PIR_PIN = 25 # 22 on the board LED_PIN = 16 def main(): io.setup(PIR_PIN, io.IN) io.setup(LED_PIN, io.OUT) turned_off = False last_motion_time = time.time() while True: if io.input(PIR_PIN): last_motion_time = time.time() io.output(LED_PIN, io.LOW) print ".", sys.stdout.flush() if turned_off: turned_off = False turn_on() else: if not turned_off and time.time() > (last_motion_time + SHUTOFF_DELAY): turned_off = True turn_off() if not turned_off and time.time() > (last_motion_time + 1): io.output(LED_PIN, io.HIGH) time.sleep(.1) def turn_on(): subprocess.call("sh /home/pi/lights_on.sh", shell=True) def turn_off(): subprocess.call("sh /home/pi/lights_off.sh", shell=True) if __name__ == '__main__': try: main() except KeyboardInterrupt: io.cleanup()And the script (lights_on and lights_off) which will be executed by detection looks like this:
lights_on:

That kind of does what I want in a round about way, I do want the sliders though as I do want to be able to control the colour, I do there is a python script which does just this from a book entitled “Programming the raspberry pi” the author has a github which has open access to the script. Essentially the script opens up a Tkinter window with sliders for each colour. Would it be possible to incorporate the sliders into a module, I’m a little fuzzy on how the modules work if they are entirely JavaScript or if HTML is possible?

So I’ve found another possibility to do everything I need, I found a website showing me how to setup a secondary web server to control the led strip, I’ve modified it to my specifications but I’m stuck on how to implement it into my mirror. I am able to view the webpage via my pi’s ip and port however the webpage won’t seem to work in an iframe module as I had hoped.
