This project presents us a modular matrix led display based on the ATmega48 micro-controller. The main feature of this modular matrix display is that you can reconfigure it to form an arbitrary lenght LED display. Due to the simplicity of the design, it is easy to extend the communications protocol to more than one display chain to increase the height of the display. In this project, both single and double row examples are shown.
