CODE | LED Dot Matrix Display Pong Game - Arduino Project 022
This project was hard going and a lot to take in. So, for Project 22 you are going to create a simple game with simple code using the dot matrix display and a potentiometer. This time you are going to use one of the many available libraries for controlling LED dot matrix displays to see how much easier it can make your life when coding.
