Introduction: 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.

Step 1: Components Required

Picture of 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:

Picture of Circuit:

Make connection as shown in the schematic diagram.

Step 4: Source Code

The source code can be obtained from my GitHub profile. Click here

Yea, but can you make the seven segment displays do that exact same thing without the Arduino Micro-controller? We used to do that with building our own oscillator and circuitry. Makes you learn more about how things really work. Nice project either way. I am glad to see younger folks getting into electronics even if it is always a Arduino controller circuit.

Thank you, we are here to learn unknown concepts of course. I'll be glad to learn your concept too. Could you please share it with us??
