3. 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.

4. 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).

5. Components

6. 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.

8. 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.

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

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