Hi,the following is the circuit of a clap switch. components:
C1 = 741 OP AMP, C2 = 555 TIMER, C3 = 4013 Dual D Flip Flop, Q1 = 2N2222 NPNC1, C2, C3, C4 = .1 uF DISC, C5 = .47 uF Electrolytic R1, R2, R4, R5, R10 = 10,000 ohms, R6 = 150,000 ohms, R7, R9 = 100,000 ohms, R8= 1megaohm R11 = 220 ohms, R3 = 100,000 ohm trimmer POT, B1 = 9v Battery, K1 = SPST reed Relay 5v DC coil, MIC = Electronic Microphone

What happens inside a CLAPPER:it has an audio amplifier that has a limiter on the input. Any audio signals that are below a particular threshold will not get through.When the sound pressure level gets above a certain level it triggers the amplifier which is set to clip รข€“ switch on.This on signal is the trigger to turn on the lights.
