How It Works

• An OLED display (SSD1306, I2C) is driven directly by the Arduino, redrawing the game screen frame by frame from a pixel buffer.
• Push buttons wired with pull-down resistors provide directional/action input, debounced in software to avoid false repeated presses.
• A game loop reads input, updates game state (snake position, falling block position, collisions), and redraws only the changed pixels for smooth performance.
• Game speed and difficulty scale by adjusting the loop delay as the game progresses.

Components

Arduino Uno/Nano
0.96" OLED display (SSD1306, I2C)
4-5 push buttons (directional + action)
Buzzer (optional sound effects)
Battery pack + enclosure

Applications

• Educational demonstration of embedded graphics programming
• Portable hobby entertainment device
• Teaching game-loop and collision-detection concepts

Advantages

• Runs entirely offline, on minimal, inexpensive hardware
• Demonstrates real-time rendering and input handling, skills that transfer beyond gaming
• Fully portable, battery-powered handheld form factor

Sample Code — OLED Game Loop Outline

// Simplified game loop - Arduino + SSD1306 OLED
#include 
Adafruit_SSD1306 display(128, 64, &Wire, -1);
int btnUp = 2, btnDown = 3, btnLeft = 4, btnRight = 5;

void setup() {
  display.begin(SSD1306_SWITCHCAPVCC, 0x3C);
  pinMode(btnUp, INPUT_PULLUP);
  pinMode(btnDown, INPUT_PULLUP);
  pinMode(btnLeft, INPUT_PULLUP);
  pinMode(btnRight, INPUT_PULLUP);
}

void loop() {
  display.clearDisplay();
  readInput();          // check button states, update direction
  updateGameState();    // move snake/block, check collisions
  drawGameState(display); // redraw pixels
  display.display();
  delay(150);            // controls game speed
}
