Sun Tracker Design Based on AVR

For more transformation efficiency, a kind of design method for sun tracker is presented. Using simplified circuit, the tracker can follow the round of sun, which can keep the surface of the solar battery perpendicular to the ray of the sun to obtain the greatest area of light as possible. Also, some parameters, such as local latitude, local time etc. are needed to input by operators. The results of experiment are demonstrated the validation of the sun tracker.
