Project 21 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.
The parts required are the same as Project 21 with the addition of a 10KΩ Potentiometer
Same as Project 21 plus….
Leave the circuit the same as in Project 21 and add a potentiometer. The left and right pins go to Ground ...
