This solar tracker system uses the Arduino UNO board, a servomotor, 2 LDRs and 2 resistors to rotate the solar panel towards the Sun or a source of light.

To do this in Arduino/C code, a new intermediate position for the servo is specified for each main loop until it reaches the final position.

Maker Michael Klements has built a unique electromechanical clock using a little Arduino hardware, code, and 28 servos, which tilt panels to reveal the correct time in digital format. As the time ...
