Abstract
So far you have dealt with individual 5mm LEDs. LEDs can also be obtained in a package known as a dot matrix display, the most popular being a matrix of 8×8 LEDs or 64 LEDs in total. You can also obtain bi-color dot matrix displays (e.g. red and green) or even RGB dot matrix displays, which can display any color and contains a total of 192 LEDs in a single display package. In this chapter, you are going to deal with a standard single color 8×8 dot matrix display and learn how to display images and text. You will start off with a simple demonstration of creating an animated image on an 8×8 display and then move onto more complex display projects. Along the way, you will learn the very important concept of multiplexing.
