This is an example for our Monochrome OLEDs based on SSD1306 drivers

Alternatively, you can copy the code below. Therefore, change the address from 0x3D to 0x3C before uploading the code onto the Arduino board. I would be using the Adafruit sample code with a minor tweak, since the address of my OLED Display is different from the one used in their sample code. For more information about the Wire library, visit. Why wire the SDA and SCL to (Analog pin) A4 & A5? Since the Adafruit library uses the Wire Library, the pins for the SDA & SCL pins are defined to be at A4 & A5 for I2C communication. For the power supply of the Display, you can either power it at 5V or 3.3V. For UNO boards that are before revision 3, you can only wire it one way: which is at the analog input area. Please note that if you are using an revision 3 Arduino Uno board, you have 2 options: wire it at the analog input area or the pins beside the AREF pin. If there is no such folder, create one.ģ) Repeat step 2 for the Adafruit GFX library.Ĥ) Wire the arduino as shown below. (Which is most likely found in "My Documents/Arduino"). Place the Adafruit_SSD1306 folder inside your /libraries/ folder. Rename the extracted folder to Adafruit_SSD1306. Both libraries are required to interface the Arduino to the OLED Display.Ģ) Extract the Adafruit_SSD1306-master.zip.

We express our utmost gratitude to Adafruit & u8glib for making their Graphic Libraries Open Source and available! Componentsġ) Download the following libraries below. The tutorial will be split into two parts, starting with the Adafruit graphics library, followed by the U8glib library. There are 2 libraries for available for interfacing the OLED Display, which is: In this tutorial, I’ll be showing you how you can use 2 different libraries to interface a I2C OLED Display with the Arduino Uno, therefore you have an option to choose either 1 of the library to use. Time to interface a 0.96" graphical OLED I2C Display with a Arduino Uno! This tiny OLED Display is useful in displaying various data from sensors, graphics and many more. #error ("Height incorrect, please fix Adafruit_SSD1306.h!") – Adafruit.
