The LoL Shield for Arduino is a charlieplexed LED matrix for the Arduino. All the LEDs are individually addressable, so you can use it to display anything in a 9×14 grid. Scroll text, play games, display images, or whatever else you want with the Lots of LEDs shield.

J Bremnant used two 16×24 led matrix boards and wrote code to make them display information of trading environment. He wanted to make something flexible that can make the best out of LED. He not only wanted scrolling text messages, but render monochrome animations and images through it. To drive the display he used Teensy 2.0 and the code is under 8K as graphics are manipulated on PC.

This project is a great little LED portable game system based on PIC16F628A. It is equipped with a 4×4 LED matrix, a PIC microcontroller, 9 bipolar transistors, 4 buttons for control and one switch to power on. It is also has a small speaker to generate game sound. It is powered from 4 Ni-MH batteries. Check this instructable on the link below. So far it has only three games programed.

This project is a LED matrix display able to display news headlines on scrolling format. The main board features a Microchip PIC18F2525 microcontroller connected to a WIZnet WIZ810MJ Ethernet module, which uses the W5100 to provide an easy-to-use interface to the Internet.

This project is a big LED matrix controlled by Arduino board and build inside an IKEA table.
The displays are connected to the Arduino to share the row select pins (A,B,C and D) and the control lines EN, CLK & LATCH. The serial lines R1,R2,G1,G2 have their dedicated pins. So there are 19 pins needed out of possible 20 (not counting the reset pins as I/O). As the displays are loaded in 16 rows a 64bit some transformation has to be done while loading the display.

The device comprises two parts: LED control board and LED display board. The two PCBs are designed to fit together one behind the other using two sets of dual row connectors and 4 spacers. One of this connector is used for the electrical connections, while the other is only used as a mechanical connecting element.

This project shows how to build a Digital clock with 32×8 LED matrix display based on ATmega168 microcontroller. It doesn’t use a RTC timer chip but timer interrupt triggered via external crystal at 32.678kHz. It allows generating exact 1sec intervals while AVR is running with internal system clock at 8MHz.
