ECE Project on Clap Switch

Clap Switch is a switch which can switch on/off any electrical circuit by the sound of the clap and for this interesting reason we have choose this project as a Mini project for Electronics Engineer. The basic idea of clap switch is that the electric microphone picks up the sound of your claps, coughs, and the sound of that book knocked off the table. It produces a small electrical signal which is amplified by the succeeding transistor stage. Two transistors cross connected as a bi-stable multi-vibrator change state at each signal. This circuit is constructed using basic electronic components like resistors, transistors, relay, transformer, capacitors.



The operation of the circuit is simple. If we clap the lamp turns on and to switch it off clap again. The condenser microphone picks up the sound of your claps, coughs, and the sound of that book knocked off the table. It produces a small electrical signal which is amplified by the succeeding transistor stage. Two transistors cross connected as a bi-stable multi-vibrator change state at each signal. One of these transistors drives a heavier transistor which controls a lamp. This circuit can switch on and off a light, a fan or a radio etc by the sound of a clap.

The basic principle of this clap switch circuit is that it converts sound signal into electrical energy. The input component is a transducer that receives clap sound as input and converts it to electrical pulse. The basic idea of clap switch is that the electric microphone picks up the sound of your claps, coughs, and the sound of that book knocked off the table.
