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,
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
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.
