Introduction: LED Blinker Using 555 IC
Today I am going to make an LED Blinker using timer IC 555.
Let's get started,
Step 1: Take All Parts As Given in the List
Components required -
(1.) Timer IC - 555 x1
(2.) Resistor - 1K & 10K x1
(3.) Power supply - 5V DC
(4.) Capacitor - 16V 100uf
(5.) LED - 3V x2
Step 2: Connect All Components -
Connect all components on 555 timer IC as shown in picture.
NOTE: we can connect all 8-LEDs if you want then connect.
Step 3: Solder Pin 4 & 8
First connect pin 4 and 8 of 555 timer IC
Step 4: Solder All Components
Solder all components according to the circuit diagram.
Step 5: Give Power Supply
Now circuit is ready .
Give power supply 5V DC to the circuit.
Connect +Ve of power supply to pin 8 of 555 IC and
-ve of power supply to the pin 1 of 555 IC.
Now LED is starting blinking one by one.
