I may make a commission if you buy the components through these links. Due to its popularity, I decided to make a very detailed tutorial on how to use the common Anode and common Cathode seven segments with Arduino. Common Anode and common cathode type seven segment displays are widely used in electronic meter, Temperature display system, RPM monitoring gadgets, digital clocks, and other electronic devices that display numerical information. In this tutorial, you will learn how to use a seven segment display with Arduino Uno.
