Self Configuring and Modular LED Matrix Display

May 19, 2010 By: admin Category: AVR, Display, LED, Project No Comments →

The goal of the project is to build a self-reconfiguring LED Dot matrix display. It uses ATmega48 based modular LED matrix display unit, Kingbright TA20-11EWA LED matrix array, which can be chained together to form a self reconfiguring and arbitrary length LED matrix display. A head unit consisting of an ATmega168 is placed at the […]
