I don't know what language your using, or what micro-controller your using. But I have created a project a while ago that automatically opens / closes my blinds. I used an AtMega168 AVR micro-controller, and my code is in C. Basically, it uses the ADC to read how light / dark it is, then decides what to do based on the lightness value.
