OLED Graphic Display Interfacing with NodeMCU

This guide shows how to use the 0.96 inch SSD1306 OLED display with ESP8266 using Arduino IDE. We’ll show you how to write text, set different fonts, draw shapes and display bitmaps images.

The OLED display doesn’t require backlight, which results in a very nice contrast in dark environments. Additionally, its pixels consume energy only when they are on, so the OLED display consumes less power when compared to other displays.The model we’re using has four pins and communicates with any microcontroller using I2C communication protocol. There are models that come with an extra RESET pin or that communicate using SPI communication protocol.
