Hi,
here´s (https://github.com/McNugget6750/pypilot-.../Motor.pdf) a shematic from one possibility to build a motorcontroller. You can see there´s a Pin (D7) witch can be used for a LED.
It´s possible to use PWM for the backlight and I think there´s a GPIO Pin free for using it. But my direction was a very easy way and I didn´t want a "Auto"Backlight. I just set the backlight once. First I use a trim potentiometer and after once set to the right point I see that was 2,5kohm so I use this value.
Best regards
Andreas
