This project makes a stepper motor control the position of a solar panel to make it turn to the position that it recieves the most light from the sun.
After sundown (light dims below a set level) the unit turns towards the 'morning' position. (east)
The software that drives the Arduino is included in its latest version. But it is being worked on to make things work perfectly. Current version doesn't support returning to morning position, but will be added soon.
