## What it is
An Arduino library for driving monochrome OLED displays based on the SSD1306 controller chip, supporting 128x64 and 128x32 panels over I2C or SPI. It works with the Adafruit GFX library to provide drawing primitives like lines, circles, and text on small embedded displays.

## Use cases
- display text and graphics on a 128x64 OLED with an Arduino
- drive an SSD1306 OLED over I2C on an ESP8266
- draw shapes and scrolling text on a small monochrome OLED
- interface a 128x32 OLED display with SPI on an AVR microcontroller
- add a status screen to an embedded sensor project

## When to choose
- you have an SSD1306-based monochrome OLED and program with the Arduino IDE
- you want a mature, well-tested library with Adafruit GFX integration
- you need flexible I2C or SPI pin configuration on AVR, ESP8266, or similar MCUs

## When to avoid
- you use a color OLED or a different controller chip like SH1106
- you need grayscale or high-resolution displays
- you are not programming in the Arduino ecosystem

## Facets
- artifact type: library
- maturity: stable
- function: graphics, embedded, sdk
- domain: embedded-systems, hardware, developer-tools
- platform: embedded, cpp, iot
- tags: arduino-library, ssd1306, oled-display, i2c, spi, monochrome-display, adafruit-gfx
