1 light bulb and 1 lithium battery | Repair led light
This is a circuit project that controls a light bulb using DC power from a battery. In this project I used a Scr semiconductor relay combined with a DC power source from a lithium battery to switch 220V AC. This lamp control circuit project is widely used in industry. You absolutely can do it, watch this video to the end. Thanks for watching!
