Both these libraries are available from Adafruit. The GFX library provides graphics functions for displaying text, drawing lines and circles, etc. The SSD1306 driver library is used to initialize the display and provide low level display functions.

Two Arduino libraries must be installed to start using the display. Pin connections for wiring an Arduino MEGA 2560 to the OLED display are as follows.Īrduino OLED I☬ Libraries for SSD1306 and Graphics Functions

How to Connect the Geekcreit 0.96 Inch OLED I2C Display to Arduino – Wiring Diagram Arduino MEGA 2560 OLED Wiring Pin connections are as follows for wiring the OLED display to an Arduino Uno. The image below shows how to connect the Geekcreit 0.96 inch OLED I2C display to Arduino. Geekcreit 0.96 Inch OLED Display I2C/TWI Pinout Arduino Uno OLED Wiring Don't blow up your display!Īlso make sure that your display is 5V compatible as this one is. Some modules have GND and VCC swapped around. If the pins are swapped, make sure to change the connections to the Arduino – OLED VCC connects to 5V on the Arduino, OLED GND to GND on the Arduino.Ĭaution! Make sure that you connect the power pins correctly. Check your display to make sure that it is the same as the image below. The first and most important thing to note is that some of the displays may have the GND and VCC power pins swapped around. How to connect the Geekcreit 0.96 Inch 4 pin white I2C OLED module to Arduino How to Connect the Geekcreit 0.96 Inch I2C OLED Display to Arduino These libraries are installed in this tutorial. Libraries are available that make it easy to start using the display right away to display text and graphics. This interface is sometimes called TWI (Two Wire Interface).Īt the very lowest level, the Arduino Wire library is used to communicate with the display. The data connection is I2C (I☬, IIC or Inter-Integrated Circuit).

The display connects to Arduino using only four wires – two for power and two for data, making the wiring very simple. Libraries are then installed and some example programs run which show how to use the display in an Arduino sketch. In this tutorial a 0.96 inch monochrome OLED display from Geekcreit is connected or interfaced to an Arduino.
