How to Make Amazing Sound Producer Using LM555 IC

Hii friend,

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,

Step 1: Take All Components As Shown Below

Components required -

(1.) Speaker - 8 ohm

(2.) IC - LM555

(3.) Resistor -1K

(4.) Capacitor - 16V 10uf

(5.) Ceramic capacitor - 100 nf (104)

(6.) Battery clipper

(7.) Battery - 9V

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.
