Clapping Switch With BC547 Transistor

About: Share diy projects to those who have the same hobby with me

Hii Friend,

Today I am going to make a circuit of Clapping switch with BC547 Transistor.In Earlier We made clapping switch using LM555 IC.

Let's get started,

Teacher Notes

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Take All Components As Shown Below

Components required -

(1.) Transistor - BC547 x1

(2.) Microphone x1

(3.) Capacitor - 25V 47uf x1

(4.) Resistor - 1M x1

(5.) Resistor - 10K x1

(6.) Resistor - 120K x1

(7.) Battery - 9V

(8.) Battery clipper

(9.) LED - 3V x1

(10.) Resistor - 220 ohm x1

Step 2: Transistor - BC547

C - Collector

B - Base and

E - Emmiter

Step 3: Circuit Diagram

This is the circuit diagram of this project.

Connect all components according to this circuit diagram.

Step 4: Connect Both Transistors

Firstly we have to connect both transistors.

Solder Collector Pin of transistor-1 to Base pin of transistor-2 as solder in the picture.

Step 5: Connect 47uf Capacitor

Next we have to connect 47uf capacitor.

Solder -ve pin of capacitor to base pin of transistor-1.

Step 6: Connect Emmiter Pin of Both Transistor

Next Solder emmiter pin of transistor-1 to transistor-2 as solder in the picture.

Step 7: Connect 10K Resistor

Solder 10K Resistor to +ve pin of capacitor.

Step 8: Connect 1M Resistor

Next solder 1M Resistor to base pin of transistor-1.

Step 9: Connect 120K Resistor

Solder 120K Resistor to collector pin of transistor-1 as solder in the picture.

Step 10: Connect 220 Ohm Resistor

Solder 220 ohm resistor to -ve leg of LED.

Step 11: Connect LED to Circuit

Solder 220 ohm resistor which is connected to -ve leg of LED to the Collector Pin of Transistor-2 as solder in the picture.

Step 12: Connect +ve Leg of LED

Solder +ve leg of LED to 10K,1M and 120K resistor as you can see in the picture.

Step 13: Connect MIC

Solder +ve wire of MIC to +ve pin of Capacitor and

solder -ve wire to emmiter pin of Transistors as you can see in the picture.

Step 14: Connect Battery Clipper Wire

Now we have to connect battery clipper wire to the circuit.

Solder +ve wire of battery clipper to +ve leg of LED and

solder -ve wire of battery clipper to Emmiter pin of transistors as you can see in the picture.

And Connect Battery to battery clipper.

To activate LED Do Clap.

Thank you
