Hi I have build a setup where there are two RC motors to drive a mirror which is 2 dimensional. I have been thinking to write a program in Arduino such that after tracking (from solar tracker which i already made) the sunlight , the mirror should always be reflecting on a desired angle no matter where the sun is. I am trying to think of any ideas how this could be implemented. But I could not get anywhere, I hope i could get some advice on this. I am thinking to start with horizontal axis only for the moment. so how could this be implemented. If the Sun rises from East and sets to west I want the mirror to reflect on a specific angle all day, say its 30 degrees for example.
