Story

What is Seven Segment display?

Seven Segment display

It is an alphanumeric display.

It contain 7 leds.

It is used in digital clock, electronic meters, basic calculators, and other electronics devices.

It has two type common anode & common cathode.

Common Cathode.

In common cathode all the cathode pins are connected with the ground.

2. Common Anode.

In common anode all the anode pins are connected with the 5 volt.

Circuit diagram of both the type of seven segment display

About the Project.

in this project Arduino Uno is used as a Microcontroller and for making display leds are used where one segment of display is represented by the two Leds.

As it is a Common cathode Seven segment so all the cathode pin is connected with the ground.

STEPS::-

Take a breadboard and fixed the all 14 leds as shown in the diagram.

2. After that connect these leds with arduino uno according to the circuit diagram.
