Project 19 – LED Dot Matrix Display – Basic Animation
In this project, you shall again use two sets of shift registers. These will be connected to the rows and columns of the dot matrix display. You will then show a simple object, or sprite, on the display and animate it. The main aim of this project is to show you how a dot matrix display works and introduce the concept of multiplexing because this is an invaluable skill to have.
You will need two shift registers (74HC595) and eight current-limiting resistors. You also need to obtain a common anode (C+) dot matrix display and the datasheet for the display so you know which pin connects to which row or column.
