If you like LED display project here is another cool project : Arduino based POV globe. This persistence of vision project able to displaying monocolour bitmaps up to 72 pixels high and x width. (uses 72 LEDs, and one input to get rotation speed). The main component in this project is atmega328P, 72 SMD [...]

This project shows you how to interfacing touch LCD with 8-bit AVR Atmega644. The device can do some trick what iPhones can do. Since the project powered with 8 bit 12Mhz AVR, it run slower than iPhone (417Mhz ARM). But, It’s cool project, iPhone vs AVR

Led 3D-ball is 3D lights effects project based on microcontroller AVR AT90S2313 and 2 decoder 74145. The project could be use as decoration balls for Xmas and New Year trees, bars, cafes, disco and more. The matrix measuring twenty rays all over seven led. The microcontroller firmware written in basic and compiled with bascom AVR.

The Electronic Mini-Badge project is a PIC24FJ64GA004-based electronic badge that displays color slideshows. Many electronic badges display scrolling text using a matrix of discrete LEDs. This low-power system features a graphical OLED display and can be easily upgraded to handle animation, video, or RF communication.
The PIC24FJ64GA004 microcontroller is used as a compromise between the speed [...]

Project description:
For my final design project I decided to design and build a digital dot matrix message device. I’ve seen devices similar to this before and I wanted to find out if I could build one myself. The display consists of 7 LEDs in a vertical row. By moving them fast enough back and forth [...]
