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.
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).
Required Components
As already mentioned, this project is basic Electronics mini-project, so this project is made of the basic components. Following is the list of the components required to make the Clap Switch.
1.1K, 4.7K, 47K, 330 and 470 ohm resistors
2.10µF and 2 100nF capacitors
3.Electric Condenser mic
4.Two BC547 transistors
5.LED
6.555 timer
7.9V Battery
