AVR Pong Game

This project recreates the game Pong by programming it directly on a ATmega328P microcontroller using C++. Doing this project was really satisfactory, as it was my first experience programming hardware. I came up with it as my final project for the subject EE 120B.

Play it here!

The approach was to design the logic of each component separately as a state machine and then implementing all together. The logic diagram of the final implementation was the following:

• Hardware components used

  -Arduino UNO R3 Controller Board (ATmega328P microcontroller)

  -ST7735 LCD (used as primary screen)

  -LCD 1602 (used as secondary screen)

  -x2 Joysticks

  -Button

  -Resistance 10kΩ

• Wiring Connections

  • ST7735 LCD
