This is a small circuit that acts as a sound activated switch. The ic used is ne555 wich is known as the multi vibrator or timer IC.
Components :
IC ne555 - 1
Transistor BC547 - 2
Condenser Mic - 1
Resistor 4.7k - 1
470R - 2
1K - 1
47K - 1
Capacitors 100n - 2
100uf - 1
LED - 1
Battery 6V
NoTe :
You can also use the Transistor BC548 instead of BC547 ...... :)
