Simple Switch
(OP)
I want to use a 2N2222 transistor to switch on and of Christmas light using a microcontroller. The collector and emitter of the transistor is in series with the Christmas lights wire. The base of the transistor is connected to a 5 Volt output of a microcontroller. My question is do I need a common ground? If so where would be the best place for it? I tried to hook up the circuit but nothing happens. Help!!!
