Light alarm

This is a simple robot that turns on the lights after a certain amount of time. It turns a dimer that is connected to extension cords. Overall this is pretty simple – I only made one program and that program counts down till the alarm then goes off when time is up. You can download the program here. There will be a second version that works with normal room light switches – I’ll post about that soon.

Also – the belt looks really loose in the pictures but you’ll notice in the video that there is a weight on the back of the board that stops the board from bending and keeps the belt tight.
