How to Make LED Blinker Using LM555 IC

Hii friend,

Today I am going to make LED Blinker circuit using LM555 IC.This is a timer IC.To make this circuit we will require very less components.

Let's get started,

Step 1: Take All Components As Shown Below

Components required -

(1.) IC - LM555 x1

(2.) Resistor - 1K x2

(3.) Capacitor - 25V 220uf / 25V 100uf x1 {We can use capacitor of 16V/25V/63V}

(4.) LED - 3V x1

(5.) Battery clipper x1

(6.) Battery - 9V x1

Step 2: Circuit Diagram

This is the circuit diagram of this project.

Connect all components to the IC according to circuit diagram.

Step 3: Solder Pin-4 and Pin-8 of the IC

Firstly we have to solder pin-4 and pin-8 of the IC as solder in the picture.

Step 4: Solder Pin-2 and Pin-6

Next solder pin-2 and pin-6 of the IC as solder in the picture.

Step 5: Connect 1K Resistor

Next connect 1K resistor between pin-6 to pin-7 of the IC as you can see in the picture.

Step 6: Again Solder 1K Resistor

Next again we have to solder 1K resistor between pin-7 to pin-8 of the IC as you can see in the picture.

Step 7: Connect Capacitor

Next solder capacitor to the IC.

Solder +ve pin of the Capacitor to pin-2 and -ve pin of capacitor to pin-1 of the IC as solder in the picture.

Step 8: Now Connect LED to the Circuit

Solder +ve leg of LED to Pin-4 of the IC and -ve leg of LED to Pin-3 of the IC as solder in the picture.

Step 9: Connect Battery Clipper Wire

Solder battery clipper wire to the circuit.

Solder +ve wire of battery clipper to Pin-8 and -ve wire of Battery clipper to Pin-1 of the IC as you can see in the picture.

Step 10: Circuit Is Ready

Connect Battery to the battery clipper and now we will get the result "LED is blinking".

This type we can make LED Blinker circuit using LM555 IC.If you want to make more electronic projects like this then follow utsource123 now.

Thank you.
