How to Show Text & Sensor Data on a 0.96″ OLED with Arduino

The tiny 0.96″ OLED display is a favourite for Arduino projects — it’s crisp, low-power and needs just two signal wires (I²C). In this guide you’ll print text and sensor values on it.

What you’ll need

• Arduino Uno R3 — drives the display
• 0.96″ OLED Display (I²C) — shows your text and data
• Jumper Wires — to connect it

Wiring (I²C)

• VCC→5V, GND→GND
• SDA→A4, SCL→A5 (on an Arduino Uno)

The Arduino code

Install the Adafruit SSD1306 and Adafruit GFX libraries from the Library Manager, then:

#include <Wire.h>
#include <Adafruit_GFX.h>
#include <Adafruit_SSD1306.h>
Adafruit_SSD1306 display(128, 64, &Wire, -1);

void setup(){
  display.begin(SSD1306_SWITCHCAPVCC, 0x3C);  // I2C address 0x3C
  display.clearDisplay();
  display.setTextSize(2);
  display.setTextColor(SSD1306_WHITE);
  display.setCursor(0,0);
  display.println("Arduino");
  display.println("Corner");
  display.display();
}
void loop(){ }

Change the text or feed it a sensor reading (e.g. temperature or distance) to build a live display.
