A pong matrix tutorial?! Heck yes.
Picture of Arduino based Bi-color LED Matrix Pong Game
We have created two game project instructables so far using the jolliFactory Bi-color LED Matrix Driver Module D.I.Y kits we designed. This LED Matrix module is designed to be chain-able so you may daisy-chain the modules together to the number of modules you need to suit your project.
You may check out these two game project instructables with the links below:
Project to build a 2 LED Matrix tall Tetris game can be found at http://www.instructables.com/id/Arduino-based-Bi-color-LED-Matrix-Tetris-Game/

Pong is one of the first computer games ever created. We came across a couple of Pong game projects built using potentiometers to control the paddles. Potentiometer is not expensive, easy to work with and thus is a great choice as an input device for Pong game projects.
