The amplifier circuit used here is made using 2N3904 npn transistor to amplify the small voltage developed by the mic , into a enough voltage to light up the LED's.
Components used :
1 . 2N3904 transistor - 1
2 . 10k resistor - 2
3 . 100k resistor - 1
4 . 104 ( 100nF ) capacitor - 1
5 . LED 5mm - 1
6 . Condensor mic - 1
7 . 5v dc supply
8 . Soldering iron , soldering wire
