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 8x8 LEDs or 64 LEDs in total. You can also obtain bicolor 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 8x8 dot matrix display and show you how to display images and text. You will start off with a simple demonstration of creating an animated image on an 8x8 display and then move onto more complex display projects. Along the way, you will learn the very important concept of multiplexing.
