This meant using 42 dual-colour LED’s, which would require a large number of GPIO pins on the micro-controller. Using a clever combination of matrix and charlieplexing techniques, he was able to ...

Using some cheap transistors, common red LEDs, and a PIC16F628, he is able to drive a 6×6 LED matrix. This project is very well documented and has everything available including: circuit board ...

The LED driver enables the IS31CS9310 and IS32CS9310 to create LED matrix light tailored to system ... light is tackled with a de-ghosting circuit in the IS31CS9310 and IS32CS9310.

Connect pins according to the instructions given above, and download the sketch into Arduino board. If everything seems right, you can power up the Arduino (and the LED matrix) to see the LED matrix ...
