My home cinema screen lifter + other features

I built a rigid screen for my projector some years ago, and recently I had the idea to motorize it.
So I made a system that control the lift of my screen, the night light and the temperature of my electronical stuff.

I explain almost everything in this video : Arduino screen lifter and home theatre system - YouTube

here the code : GitHub - Benn25/Screen_UP_DOWN: Arduino project, videoprojector framed screen lifter. also control a LED tape light with 4 timers and fans for cooling your electronic stuff

If you have some comments, good or bad, or questions, please go ahead!
