The SSD1306 OLED — 4-pin I2C vs 6-pin SPI, wiring it in 4 wires, and a large library of text animations and shape drawing: scroll, typing effect, zoom, bounce, wipe transitions, signal-strength bars.

Objectives: Wire an SSD1306 over I2C · Compare I2C and SPI trade-offs · Use Adafruit GFX/SSD1306 to draw text and shapes

Components: 0.96″ SSD1306 OLED (I2C) · Arduino Uno · breadboard & wires

Libraries:

  • Adafruit SSD1306
  • Adafruit GFX
