Introduction: Clap On/off Switch

Picture of Clap On/off Switch


Hi i'm sadaf

here i made my first clap on/off switch.

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.

1K, 4.7K, 47K, 330 and 470 ohm resistors

10µF and 2 100nF capacitors

Electric Condenser mic

Two BC547 transistors


555 timer

9V Battery

Advantages & Disadvantages
It can used to turn ON and OFF the LED or LAMP simply, by clapping your hands.We can also remove LEDs and place a FAN or any other electric component on the output in order to get desired result.The Condenser Mic used in this circuit has the short range as a default, which cannot be varied

till how far does the mic hear

it is ok that with your clap the led will glow. But can you provide a circuit diagram for your DIY. I want to make it...

hazel eye made it! (author)Tech Works2016-02-04

sure :)
