A clap switch circuit is a classic beginner s project.
Equipment can be switched on and off by just clapping your hands. Add a tiny microcontroller and you can easily build-in some more useful features.

The microcontroller in this circuit makes it a simple job to add some useful features that are not seen on other clap switch designs:

Changeover relay contacts enable the unit to be wired in conjunction with a manual changeover switch so that manual override of the switched equipment is always possible.
The unit is only responsive to a specif ....etc

An infra-red or wireless remote control has the disadvantage that the small, handy, remote transmitter is often misplaced. The sound operated switch has the advantage that the transmitter is always with you. This project offers a way to control up to four latching switches with two claps of your hand. These switches may be used to control lights or fans or anything else that does not produce too loud a sound. To prevent an occasional loud sound from causing malfunction, the circuit is normally quiescent. The first clap takes it out of standby ....etc

CLAP SWITCH


Here s a clap switch free from false
triggering. To turn on/off any ap
pliance, you just have to clap
twice. The cir-cuit changes its output state
only when you clap twice within the set
time period. Here, you ve to clap within 3
seconds.
The clap sound sensed by condenser
microphone is amplified by transistor T1.
The amplified signal provides negative pulse
to pin 2 of IC1 and IC2, triggering both the
ICs. IC1, commonly used as a timer, is
wired here as a monost ....etc
