7 Segment Display With Arduino

You will find code and circuit diagram for both common cathode and common anode seven segment displays in this article.

7 segment displays don’t look modern enough for you, but they are the most practical way to display numbers. They are easy to use, cost-effective and highly readable, both in limited light conditions and in strong sunlight.

In this project, we will display numbers from 0 to 9 as it is a single 7 segment display we can display only one digit at a time.

Components Required

1. Arduino - https://amzn.to/32jAMUA
2. 7 segment display - https://amzn.to/35p4wS5
3. Breadboard - https://amzn.to/3kdp4Rt
4. jumper wires - https://amzn.to/3iqdBxM
5. 8 X resistors of 220 ohms - https://amzn.to/2ZuPNRN

Resistance is important to apply otherwise display can burn after a few minutes.
