OLED displays are a great way to bring interactivity and visual feedback to your electronics projects. In this tutorial, we’ll walk you through how to test a 1.3-inch OLED display using an Arduino Uno and the GyverOLED library — one of the simplest and fastest ways to get started with I²C OLED modules using the SSH1106 driver.

Components Required

To get started, you will need the following components:

Components required for this tutorial

✅ Arduino UNO board

✅ OLED 1.3"

✅ Jumper Wires

✅ USB cable for Arduino

🛠️ Circuit Wiring

Here’s how to wire the components correctly:

Wiring diagram

✅ VCC (OLED) → 5V

✅ GND (OLED)→ GND

✅ SCL (OLED) → A5

✅ SDA (OLED) → A4

Install the GyverOLED Library

To make coding easy, we’ll use the GyverOLED library by AlexGyver. Open the Arduino IDE > Go to Sketch > Include Library > Manage Libraries > In the Library Manager, search for "GyverOLED" > Click Install.

This library is lightweight, fast, and supports SSH1106 out of the box.

Programming the Arduino

Here’s a simple sketch to display "HELLO WORLD" on OLED, or you can download the code HERE.

#include <GyverOLED.h>

GyverOLED oled;

void setup() {
  oled.init();  // Initialize the OLED
  oled.clear(); // Clear the display
  oled.setScale(2); // Set text size slightly smaller
  oled.setCursor(10, 2); // Set cursor position
  oled.print("HELLO WORLD"); // Display text
  oled.update(); // Refresh the display
}

void loop() {
  // Nothing needed in loop for a simple test
}

Open Arduino IDE and copy-paste the code

🧪 Test

Once the code is uploaded and your wiring is correct, you should see "HELLO WORLD". Displayed on the OLED in white or blue, depending on your module. If nothing shows up, double-check your I²C connections and OLED address.

📌 Conclusion

And that’s it! You’ve successfully tested your 1.3” OLED display using Arduino and the GyverOLED library. What you learned: OLED wiring via I2C, installing and using GyverOLED, and displaying text using Arduino.
