This a simple clapper switch circuit consisted of : op-amp,555,transistor,and a couple of resistors.
the schematic is included in the file and has the header for connecting it to a pic microcontroller.
all you need is a simple program to control the timing of the output wave of the 555.

CIRCUIT DESCRIPTION

The circuit is consisted of two main parts :

LM741 OP-AMP:
This is responsible for amplifying the microphone signals and feed them to the 555 pin2 (TRIGGER PIN)

555 timer IC:
It is The Timing stage, when a signal is reached at pin2 the 555 will output a square wave at pin3 which length is defined by the potentiometer .
the 555 is configured as a monostable.

Note: This Project May Be Optimized And Changed Any Time So Stay Tuned
