A game of 'Pong' on the 128x64 pixel OLED display.
I wrote this game for Ludum Dare's MiniLD #58 PONG:
Many implementations of PONG were sent to the MiniLD contest, and mine is here:

The 128x64 pixel OLED display uses an SSD1306 driver chip. This is a commonly-available module, but it uses a 3.3V interface voltage (the standard Arduino is 5V). I use a level-shifter based on either the CD4050 or the 74HC4050 to convert the SPI pins on the Arduino to 3.3V.
The player starts the game via a button on the Arduino digital pin 2. Control of the bat is by an analog paddle or joystick connected to the Arduino analog pin A0.
