Cemo has adapted this project for 16×16 dot LED matrix display. You can download the entire project from AVRfreaks (including demonstration movie).

    This project seems to be really good but no circuit no pcb layout nothing. It would be helpfull if you can give circuit and other details so that people like me can also try.

    Pls send schematics and pcb layout
