How to connect OLED Display with Arduino

Sharing is caring!

In this article, you will learn how to connect OLED Display with arduino step by step easily. In this tutorial I used 128×64 (0.9 inch) OLED display and Arduino uno.

About OLED Display

This display is made of 128×64 individual white OLED pixels, each one is turned ON or OFF by the controller.

In this tutorial I used i2c variant of OLED display and a SPI version is also available in market. Thsi board uses i2c 7bit address between 0x3c – 0x3D.

Since it uses i2c protocol to communicate, it is very easy to connect with Arduino.

Interfacing OLED with Arduino

Step by Step Instructions

  • Connect OLED display with Arduino Uno as connections given in the circuit.
  • Install the 2 libraries, you can download from the link at the end of article.
  • For Installing library Open Arduino IDE -> Sketch -> Include Library -> Add Zip library -> Select the library -> click open.
  • Similarly do for both libraries.
  • Now go to Arduino Directory where libraries are stored. Usually it is located in documents folder for Windows users.
  • Open libraries -> Adafruit_SSD1306-master ->Open Adafruit_SSD1306.h file.
  • Uncomment #define SSD1306_128_64 and comment the remaining both as shown in the video. Save the file.
  • Open the code and upload the code to Arduino Uno.
