Request for help: LED Control module for and 5050smd strip

disease

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:

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.
