Micro-Arcade: OLED Pong

The OLED Pong Game is a marvel of miniaturization. By utilizing the I2C protocol and specific display libraries, you can render smooth, 60 FPS graphics on a screen smaller than a postage stamp.

Graphic Engine on Arduino

Driving an OLED screen requires a "Frame Buffer."

  1. The Buffer: The Arduino allocates a chunk of its SRAM (1024 bytes for a 128x64 display) to act as an invisible canvas.
  2. Drawing: Functions like display.fillRect() calculate the math of the paddle and the ball, flipping bits in that invisible canvas.
  3. The Push: The display.display() command sends all 1024 bytes to the OLED screen in a split second, creating a smooth visual frame.

Essential Hardware

  • Arduino Uno/Nano: The processor.
  • 0.96" I2C OLED (SSD1306): The tiny screen.
  • Two Potentiometers: Used to slide the paddles up and down the Y-axis.
  • A piezo buzzer: For satisfying "blip" noises when the ball bounces.

Why use Potentiometers?

While buttons work, potentiometers provide smooth analog input. The Arduino's ADC converts the twist of the knob (0-1023) directly into the Y-coordinate of the paddle (0-64), creating the exact feel of a classic 1970s arcade cabinet dial.
