OLED’s are the future of displays, as they possess some of the greatest advantages over both conventional display technologies of LCD’s and LED‘s.

The most attractive thing about using the OLED displays is that they do not need a back-light like conventional LCD/LED screens. The organic material itself has a property known as Electroluminescence (EL), which causes the material to “glow” when stimulated by a current or an electric field. Best energy saving displays ever!!!

Getting started with the White 0.96″ I2C 128X64 OLED LCD Display Module 

This article shows how to use the SSD1306 0.96 inch I2C OLED display with the Arduino. We’ll show you some features of the OLED display, how to connect it to the Arduino board, and how to write text

Step1: Hardware required

Step2: Connecting the Hardware

Pin wiring

Wiring the OLED display to your Arduino is pretty straightforward:

Pin Wiring to Arduino Uno
VCC 5V
GND GND
SCL A5
SDA A4

If you’re using other Arduino board rather than the uno, check out what are their SCL and SDA pins.

  • Nano: SDA (A4); SCL(A5);
  • MEGA: SDA (20); SCL(21);

Step3: Setting up the library

To control the OLED display you’ll need the “adafruit_GFX” library and the “adafruit_SSD1306” library.

Installing the adafruit_GFX library

  1. Click here to download the adafruit GFX library. You should have a .zip folder in your Downloads folder
  2. Unzip the .zip folder and you should get Adafruit-GFX-Library-master folder
  3. Rename your folder from Adafruit-GFX-Library-master to Adafruit_GFX_Library (you really need ro replace those “-” by “_”)
  4. Move the Adafruit_GFX_Library folder to your Arduino IDE installation libraries folder
  5. Finally, re-open your Arduino IDE

Installing the adafruit_SSD1306 library

  1. Click here to download the adafruit_SSD1306 library. You should have a .zip folder in your Downloads folder
  2. Unzip the .zip folder and you should get Adafruit-GFX-Library-master folder
  3. Rename your folder from Adafruit_SSD1306-master to Adafruit_SSD1306
  4. Move the Adafruit_SSD1306 folder to your Arduino IDE installation libraries folder
  5. Finally, re-open your Arduino IDE

Step4: Upload the sample sketch

The following sketch displays FARANUX ELECTRONICS message in the OLED display.

#include <Wire.h>
#include <Adafruit_GFX.h>
#include <Adafruit_SSD1306.h>

#define SCREEN_WIDTH 128 // OLED display width, in pixels
#define SCREEN_HEIGHT 64 // OLED display height, in pixels

// Declaration for an SSD1306 display connected to I2C (SDA, SCL pins)
Adafruit_SSD1306 display(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, -1);

void setup() {
Serial.begin(115200);

if(!display.begin(SSD1306_SWITCHCAPVCC, 0x3C)) { // Address 0x3D for 128×64
Serial.println(F(“SSD1306 allocation failed”));
for(;;);
}
delay(2000);
display.clearDisplay();

display.setTextSize(1);
display.setTextColor(WHITE);
display.setCursor(0, 10);
// Display static text
display.println(“FARANUX ELECTRONICS!”);
display.display();
}

void loop() {

}

Step5: Testing the circuit

After uploading the code, this is what you’ll get in your OLED:

If your OLED display is not showing anything:

  • Check that the OLED display is properly wired to the Arduino
  • Double-check the OLED display I2C address: with the OLED connected to the Arduino, upload this code and check the I2C address in the Serial Monitor

You should change the OLED address in the following line, if necessary. In our case, the address is 0x3C.

if(!display.begin(SSD1306_SWITCHCAPVCC, 0x3C)) {
