Solar Tracker

Follow the sun or any light source with a low-cost stepper motor and two light-sensitive resistors, commonly known as LDRs. Attach a solar panel to the angled flange; it should be at least 5 volts and provide a current of no less than 100 mA to serve as the power source. Larger panels can also be utilized as battery chargers. If the stepper motor rotates in the wrong direction, simply reverse the 3-wire plug coming from the light-sensitive resistors. A small dead zone in the middle will prevent oscillation.
