Introduction Clap Switch is a basic Electronics mini-project, made with the help of the basic components. Clap Switch has the ability to turn ON/OFF any electrical component or circuit by the clap sound.

Introduction It is known as Clap Switch, because the condenser mic which will be used in this Project will have an ability to take the sound having same pitch as the Clap sound as the input. Although it doesn’t mean that the sound will have to be of Clap sound, it can be any sound having the same high pitch as of Clap. We can also say that it converts the Sound energy into the Electrical Energy, because we are giving an input to the circuit as a sound whereas the Circuit gives us the output as a LED glow (Electrical Energy).

Components

Working Principle of Clap Switch Circuit

when we produce some sound near condenser mic, this sound will be converted into electrical energy and it will raise the potential at the Base, which will turn the Transistor ON. As soon as the transistor becomes ON, the potential at Point A would become low and it will trigger the 555 IC because of the low voltage (below Vcc/3) at Trigger Pin 2 and LED will turn ON. We have connected the LED to Output PIN 3 of 555 IC through a 220ohm resistor.

Applications The major advantage of a clap switch is that you can turn something(e.g. a lamp) on and off from any location in the room (e.g. while lying in bed) simply by clapping your hands.

A claps witch is generally used for a light, television, radio, or similar electronic device that the person will want to turn on/off from bed.

The major disadvantage is that it's generally cumbersome to have to clap one's hands to turn something on or off and it's generally seen as simpler for most use cases to use a traditional light switch.

Advantages Energy efficient. Low cost and reliable circuit. Complete elimination of manpower. High Accuracy

DisadvantagesIf one of the device does not work properly or fails, the complete connections is lost.Activate on any sound.
