Today I am going to make amazing sound generator circuit using LM555 IC.This circuit generate sound like scooter,gun bullet shooting,whistle.
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: Solder Pin-4 to Pin-8
Firstly we have to short the pins of IC.
Solder wire between pin-4 and pin-8 of the IC as solder in the picture.
Step 3: Connect Pin-2 and Pin-6
Next Solder wire between pin-2 and pin-6 of the IC as solder in the picture.
Step 4: Connect 1K Resistors to the IC
Solder 1K resistor between pin-6 to pin-7 of the IC.
~ Again solder 1K resistor between pin-7 to pin-8 of the IC as solder in the picture.
Step 5: Connect Speaker
Solder +ve wire of speaker to Pin-4 of the IC and
Solder -ve wire of speaker to pin-3 of the IC as you can see in the picture.
Step 6: Connect 10uf Capacitor
Next solder capacitor to the circuit.
Solder +ve pin of capacitor to Pin-2 of the IC and
-ve pin of capacitor to Pin-1 of the IC as you can see in the picture.
Step 7: Now Connect Battery Clipper Wire
Now we have to solder wires of the Battery clipper.
Solder +ve wire of battery clipper to pin-8 of the IC and
Solder -ve pin of battery clipper to pin-1 of the IC as solder in the picture.
Step 8: Now Our Circuit Is Completed
Now our circuit is completed.
~ Connect battery to the battery clipper and enjoy the output sound.
Step 9: Connect 100nf Ceramic Capacitor (For Other Sound)
For different sound we need to connect 100nf ceramic capacitor to pin-1 and pin-2 of the IC as solder in the picture.
Step 10: Different Sound
Now we will get different sound comparison then before sound.
