Magic alarm clock

I’d think there should be a way to control the dimming of the display. kind of like using night mode on a smartphone. Not sure how one would get it to work off the top of my head, but I would think it would be the cheapest and probably easiest way to go about it.

You might also look at these modules:
https://github.com/Txukie/MMM-LCDControl
Sounds like they may have the LCD control you are possibly looking for…

@justjim1220 thanks for that, however it appears that it just turns off the display. I am either looking for a way to drop the backlight lower than default minimum (probably impossible) or some way of putting a layer to block most light.

For those using the official 7" display you can use MMM-Screendimmer
Or write directly to /sys/class/backlight/rpi_backlight/brightness

@emlowe Thanks, but I can’t since I use the 10.1" adafruit display, looking at the pinout it seems there is a way to control it, but I will have to manually wire it to the pi and write up a driver.
