Picture of How to Make Clapping Switch Circuit

Hii friend,

Today I am going to make a circuit of clapping switch.when we will clap then LED will glow.This circuit is amazing.To make this circuit I will use LM555 IC and C945 transistor.

Let's get started,

Step 1: Take All Components As Shown Below

Components required -

(1.) IC - LM555 x1

(2.) Microphone x1

(3.) Battery - 9V x1

(4.) Battery clipper x1

(5.) Resistor - 100K x1

(6.) Resistor - 1K x1

(7.) Resistor - 56K x1

(8.) Capacitor - 25V 10uf x1

(9.) Transistor - C945 x1

(10.) LED - 4V x1

This is good project

Hi !
Nice work!
Do you think that other NPN transistors would work? With similar or close current and voltage characteristics ?

Brings back memories of the commercial from the late 80's early 90's : The Clapper. A light bulb that would turn on and off at a clap.. Clap on . . Clap off . . The clapper. :)
