Andrew Oakley, from the Cotswold Raspberry Jam, has written an excellent tutorial in which he describes how to create a large, scrolling LED wall, controlled from a Raspberry Pi. He takes you through all aspects of the construction and powering the LEDs and includes the code to scroll messages across it. Take a look here. Here’s a video of it in action:
