This is a quick and dirty breadboard test of a solar tracker circuit based on 2 green LEDs as sensors and 3 NE555 timer chip as the control. The circuit will drive a motor to point solar panels toward the sun. You can see the motor will rotate if the plane of the sensors not facing to the sun till it's points to the sun again.
