Instructables user FreedomToCreate has made an Arduino powered system that opens and closes the blinds on a schedule, based on room temperature, or outdoor light.

Project Overview In the demonstration video below, you can learn more about this powered automatic virtual reality camera tracking system, which allows you to create light graffiti.

Inside you’ll find an Arduino board, microphone, and an 8×8 RGB module. The front cover of the project box diffuses the light using a sheet of tracing paper on a frame of foam board.
