Yes I know they have been around for over half a century, but LED displays are still a great choice for a number of applications. They are inexpensive and have great visibility and durability.

Today we will be working with both 7-segment and dot-matrix LED displays, in single and multiple modules. I’ll show you a number of different configurations of LED displays and how to wire them up and code for them.

I’ll be using an Arduino Uno for all the experiments, however, the information is equally applicable to just about any microcontroller.
