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,

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

Connect all components according to the circuit diagram.

Firstly we have to connect pins of LM555 IC using jumper wire.

connect pin-4 and pin-8 of LM555 IC as picture.

Next connect +ve pin of 10uf capacitor to pin-6 & pin-7 of the IC and

Connect -ve pin of 10uf capacitor to pin-1 of the IC as shown in the picture.

Connect 100K resistor between pin-8 of IC and +ve pin of capacitor.

Next solder emmiter pin of transistor to pin-1 of LM555 IC and

Collector pin of transistor to pin-2 of LM555 IC as you can see in the picture.

Solder 1K resistor between pin-2 and pin-4 of the IC as shown in the picture.

Now connect 56K ohm resistor between base pin of transistor and pin-4 of LM555 IC as solder in the picture.

Solder +ve wire of LED to pin-3 of LM555 IC and

solder -ve pin of LED to pin-1 of the IC.

Next connect +ve wire of battery clipper to pin-4 of the IC and

-ve wire to pin-1 of the IC as solder in the picture.

Now we have to connect wires of microphone.

Solder +ve wire of microphone to base pin of transistor and

-ve wire of microphone to pin-1 of the IC.

Connect battery to the battery clipper and clap towards microphone then we will observe that when we are clapping then LED is glowing.

This type we can make clapping circuit using LM555 IC and C945 transistor.

If you want make more electronic projects like this then follow utsource now.

Thank you
