In the last step I control a 5 volt motor with a 1.2 volt battery and the solar light IC.

They are fun to build and to teach your kids, how to work with light. The circuits are easy to build and to get working. Now to get started adding solar power to your small electronics projects and use the sun to power your battery powered night lights, garden lights, and other automated decorations or projects. Some LED drivers incorporate a voltage multiplier or voltage booster in the LED driver circuit since 1.2 volts is insufficient to power the ultra-bright LEDs. Garden lights incorporate three basic circuits, the charging circuit, the dark detecting circuit that turns the LED driver on and off, and the LED driver.
Most of the circuit designs used in automated decretive garden lights are simple and easy to reverse engineer.Īlthough it can be more work, I repair the solar cells. The ones that only need minor repairs, I repair, and the ones that need major work I strip for parts and reverse engineer the circuit boards. Each spring I gather solar lights my neighbors tossed in the garbage after the lights have stopped working.
