Use a Raspberry Pi to Display Text on a Scrolling Message Board
Small LED displays are cheap for the Raspberry Pi and fun to play with once you learn how to use them. An example would be Botdemy’s message board, which displays a message sent from a server.
The Pi hosts a web server that translates any block of text into a scrolling LED message. When you enter your message, it appears on the Pi’s display. The bulk of your work you do here is setting up a web server, but it’s not overly complicated, and it’s a great project to learn some of the basics of using the Pi’s more related features.
