Arduino Pong

This Pong clone is a learning project for the Arduino Uno (or similar).

It uses a simple potentiometer or each player's "controller," and an additional one to control the LCD screen's contrast. The buzzer plays a tone when a player scores, as well as provides feedback when the ball bounces on the wall or a player's paddle.

The title screen graphic and scoreboard font where created with img2pcd8544. You should be able to easily drop in your own assets using this tool as well.

You can play with the schematic file using the open source tool, Fritzing.

Convenience Library

This project was built using the libsangster_avr convenience library. You will need a local copy of this library to build this project. However, it is a header-only library, so it should be as simple as installing these header files to your avr-gcc's include/ directory.

Build Notes

• Don't forget to connect 3V3 to AREF. Otherwise the player controllers won't have full 10-bit resolution. If you can't move a paddle to the top or bottom of the screen, this is likely why.
• Player 1's controller directions are reversed. We assume that the players are sitting on opposite sides of the screen.
