Warning: I'm completely new to Raspberry Pi, and not even sure if it's the right solution here.
I'm trying to make a better digital picture frame. Got almost all the way there by just buying a nice flat-bezel 4k display, connecting a Chromecast, and putting a nice picture frame on it. Voila!
But I want it to adjust its brightness in response to ambient light -- and turn itself off when the room is dark. So now I need something to check a light sensor and control screen brightness.
- Video drivers with Raspberry Pi?
- Disassemble the monitor and wire it up with Arduino?
I would greatly appreciate any recommendations/suggestions/ideas.
