The source can be 3.7v battery
NPN BJT transistor
10 or 20K Resistor
LED's are connected on the opposite side
PNP does not exist, the base of the NPN will be connected to the Mic out + and the NPN emitter will be connected to the Mic out -
But since Everycircuit does not have microphones, I had to connect a PNP to make the effect of voice ON/Off
