2 Digit Seven Segment Display

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.

1. Seven segment display.

2. 220 Ohm resistors.

3. Jumper wire.

4. Breadboard.

5. Arduino UNO.

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.

Make connection as shown in the schematic diagram.
