This is a very simple Arduino project which control the 16x32 RGB LED Matrix Panel via an 16pin IDC cable. The Arduino will continuously sending 5 set colours (Red, Green, Blue, White, Black)  to the LED Matrix Panel that allow the technician to find out which part of the LED Matrix Panel is malfunction.

The story

After completing the large LED screen project, my company always left out many bad 16x32 RGB LED Matrix Panel awaiting me to diagnose. I must light up all the LED Matrix in order to find out where is the actual problem 

 

 

Source code and Downloads

To control the RGB LED Matrix Panel, you need to include the Adafruit RGB Matrix Panel library which is available at GitHub. This is an Arduino library for 16x32 and 32x32 RGB LED matrix panels, you can get more information on how to use the library on the Adafruit web site.

 Here is the test code example for this project.

Connection between Arduino and RGB LED Matrix Panel

This project is based on Arduino UNO/Duemilanove (ATMega328), however you can use it on Arduino Mega (ATmega2560) with some changes in the pin configuration.

Arduino PCB and Power Cable

This is the previous PCB design where the IDC cable is solder directly on the PCB
