Introduction: 2 Digit Seven Segment Display

About: Electronics hobbyist

Most of the newbies are confused about using two or more seven segment displays, here is an instructable showing the implementation of the same with a microcontroller.

This is possible by virtue of high switching speed of LED and high of the microcontroller.

Step 1: Components Required

1. Seven segment display.

2. 220 Ohm resistors.

3. Jumper wire.

4. Breadboard.

5. Arduino UNO.

Step 2: Pin Configuration

Please note down that I have never used the pin notation as per Arduino, rather the port wise pins have been mentioned wiz; PORTC, PORTD, etc.

The pin configuration of Arduino UNO, seven segment display(both Common Anode & Common Cathode) is as shown.

Step 3: Circuit:

Make connection as shown in the schematic diagram.

Step 4: Source Code
