Python • Re: Make this LED stay on

I suspect your problem is related to using gpiozero' to drive the LEDs.

From what I remember gpiozero resets all used GPIO to their default state when your program exits.

It could also be the GPIO.cleanup() but I don't see the function it's in ever being called.

Assuming I'm correct your options seem to include:

• Using something other than gpiozero to drive the LEDs that doesn't do this.
• Launching your program once (e.g. under a systemd service) with your measure_weight() function wrapped in an infinite loop with a suitable delay (if you want precise timing you'll need to calculate the interval each iteration).

On a related note, you seems to be importing stuff that you don't use and importing sleep twice (once under import time and again under from time import sleep
