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,
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: Circuit Diagram
Connect all components according to the circuit diagram.
Step 3: Connect Pin-4 and Pin-8 of LM555 IC
Firstly we have to connect pins of LM555 IC using jumper wire.
connect pin-4 and pin-8 of LM555 IC as picture.
Step 4: Connect 10uf Capacitor
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.
Step 5: Connect 100K Resistor
Connect 100K resistor between pin-8 of IC and +ve pin of capacitor.
Step 6: Connect C945 Transistor
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.
Step 7: Connect 1K Resistor
Solder 1K resistor between pin-2 and pin-4 of the IC as shown in the picture.
Step 8: Connect 56K Resistor
Now connect 56K ohm resistor between base pin of transistor and pin-4 of LM555 IC as solder in the picture.
Step 9: Connect Wires of LED
Solder +ve wire of LED to pin-3 of LM555 IC and
solder -ve pin of LED to pin-1 of the IC.
Step 10: Connect Battery Clipper Wire
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.
Step 11: Connect Microphone
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.
Step 12: How to Use This Clapping Circuit
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.
