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.<\/p>\n\n\n\n

We also have a dedicated guide that shows how to display temperature and humidity readings using DHT sensor and ESP8266<\/a>.<\/p>\n\n\n\n

Introducing 0.96 inch OLED Display<\/h2>\n\n\n\n

The OLED display<\/a> that we\u2019ll use in this tutorial is the SSD1306 model: a monocolor, 0.96 inch display with 128\u00d764 pixels as shown in the following figure.<\/p>\n\n\n\n

The OLED display doesn\u2019t 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.<\/p>\n\n\n\n

The model we\u2019re 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. <\/p>\n\n\n\n

OLED Display SSD1306 Pin Wiring<\/h2>\n\n\n\n

Because the OLED display uses I2C communication protocol, wiring is very simple. You can use the following table as a reference.<\/p>\n\n\n\n

Alternatively, you can follow the next schematic diagram to wire the ESP8266 to the OLED display.<\/p>\n\n\n\n

In this example, we’re using I2C communication protocol. The most suitable pins for I2C communication in the ESP8266 are GPIO 5<\/span> (SCL) and GPIO 4<\/span> (SDA).<\/p>\n\n\n\n

If you’re using an OLED display with SPI communication protocol, use the following GPIOs. <\/p>\n\n\n\n
