Small switch we call transistor is inside almost all electronic thing. But transistor cannot handle big power by itself. So we have used Simple Transistor Relay Driver Circuit which is like a special adapter for transistor. This help small signal from transistor to control big relay switch. With this we can turn ON or OFF […]
