So I'm wanting to make a lightning system for my PC, that is controlled by the sound of the speakers. The problem is I can't find out a circuit that could do this for me,
When the Sound is Loud the lights become more brighter/intense, when the sound is low the light become dim,
I know to use a NPN transistor, cuz a relay will only work as a switch. But will the NPN BJT fill up my condition. I will be experimenting on a speaker and using the current from the wires connected to the speaker magnet as my source of the transistor... Help me out
