Dear all

This circuit called as Darlington paired amplifier as per the connection u connect all the component
U just made a touch sensitive switch

U can use single transistor circuit also...



Bc547 is a npn transistor

T1 Emitter connection goes to T2 base and T1 colector goes to T2 colector


T1 base is the input of the circuit

T1 base connection goes to connect with 1k and 100k

1k resistance next end is the input of the circuit...


100k another pin goes to ground

T2 Emitter goes to gnd

12 v possitive of the circuit and 1k resistance end is the inputs of circuit

You just touch the wire ... Led will glow u can connect buzzers also...instead of LED
