0.96″ OLED display SSD1306 (128 x 64)

Description

The SSD1306 is a popular 0.96-inch I2C OLED display used in various electronics projects. Here are the key details:

1. Display Features:
   • Monocolor: The SSD1306 display is monochrome, with 128×64 pixels.
   • Contrast: It doesn’t require a backlight, resulting in excellent contrast in dark environments.
   • Low Power: The OLED pixels consume energy only when active, making it power-efficient.
2. Pinout and Wiring:
   • The SSD1306 communicates via I2C (two-wire) protocol.
   • Connect it to an Arduino Uno as follows:
     • Vin: 5V
     • GND: Ground
     • SCL: A5 (Clock)
     • SDA: A4 (Data)
3. Libraries:
   • Use the adafruit_SSD1306.h and adafruit_GFX.h libraries.
   • Install them via the Arduino IDE Library Manager.
4. Functions (for text and graphics):
   • display.clearDisplay(): Turns off all pixels.
   • display.drawPixel(x, y, color): Plots a pixel.
   • display.setTextSize(n): Sets font size (1 to 8).
   • display.setCursor(x, y): Sets text position.
   • display.print("message"): Prints text.
   • display.display(): Updates the display.
5. Testing:
   • Load an example from File > Examples > Adafruit SSD1306 in the Arduino IDE.
