Wire & Init an SSD1306 OLED
Set up the Adafruit OLED over I2C.
Meet the OLED
An OLED is a tiny self-lit screen. Each pixel glows on its own, so you get crisp text and sharp graphics with no backlight needed. 💡
The SSD1306 Chip
Most small OLEDs are driven by the SSD1306 controller. It manages the pixels for you, so your code just says what to draw, not how to light each dot.
