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 purpose of this project is to show spectrum of a sound signal from computer through a serial port to light-emitting diode matrix which is controller by microcontroller.
The Dot Matrix Spectrum Analyzer project use microcontroller AVR AT90S2313 as main part, you can change the micro with ATTINY2313. The controllers accepts the data from [...]

Do you want to learn for Scrolling Dot Matrix Display based on microcontroller? i thought this project will be great for you. The project use Basic language and Bascom AVR to compile it. The processor use At Tiny 2313.
“The Dot Matrix Display has an 5×7 led matrix with 5 columns and 7 rows.The display is [...]

This peripheral circuit designed by W.Watzig for the AT89s8252 Flash Board provides a large format, 10 character running text display using dot matrix modules.The intelligence of this project is microcontroller AT89S8252 which located in a separate microcontroller system, in the form of the Microcontroller AT89S8252 Flash Board.The actual running-text display, which can display ten characters [...]
