Description
The 0.96 Inch I2C OLED Display is a compact, ultra-bright, and low-power display module that brings a sharp visual output to any microcontroller project using just two wires — SDA and SCL. Based on the popular SSD1306 driver chip with a 128×64 pixel resolution, this display is perfect for showing sensor readings, status messages, menus, icons, and real-time data in your Arduino, ESP32, or ESP8266 projects.
Unlike LCD displays that require a backlight and multiple data wires, this OLED display emits its own light from each pixel — making it crisper, more energy-efficient, and visible even in direct sunlight. Available in Blue or White pixel colour depending on stock, it is one of the most widely used displays in Bangladesh for IoT projects, robotics, and learning electronics.
⭐ Key Features

🔧 Features & Specifications
🔧 Library Install & Setup Guide
The OLED display requires two Arduino libraries to work — Adafruit SSD1306 and Adafruit GFX. Both are free and installed directly from Arduino IDE in under 2 minutes.
Install Adafruit SSD1306 Library
Open Arduino IDE → Sketch → Include Library → Manage Libraries → Search Adafruit SSD1306 → Click Install. When prompted, also install all dependencies including Adafruit GFX Library.
Wire the Display
Connect 4 wires only — VCC → 3.3V or 5V, GND → GND, SDA → SDA pin (A4 on Arduino Uno, GPIO21 on ESP32), SCL → SCL pin (A5 on Arduino Uno, GPIO22 on ESP32).
Confirm Your I2C Address
Not sure which address your display uses? Go to File → Examples → Wire → i2c_scanner and upload it. Open Serial Monitor at 9600 baud — it will print the exact I2C address of your display (usually 0x3C or 0x3D).
Run the Example Sketch
Go to File → Examples → Adafruit SSD1306 → ssd1306_128x64_i2c. Make sure the address in Adafruit_SSD1306 display(128, 64, &Wire, -1) matches your display. Upload and watch the demo run on screen.

💻 Quick Start — Example Code
🖥️
Example 1 — Display Hello World Text
#include <Wire.h> #include <Adafruit_GFX.h> #include <Adafruit_SSD1306.h> // Define display dimensions #define SCREEN_WIDTH 128 #define SCREEN_HEIGHT 64 #define OLED_RESET -1 // No reset pin #define I2C_ADDRESS 0x3C // Try 0x3D if blank screen Adafruit_SSD1306 display(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, OLED_RESET); void setup() { Serial.begin(115200); if (!display.begin(SSD1306_SWITCHCAPVCC, I2C_ADDRESS)) { Serial.println("SSD1306 not found! Check wiring & address."); while (1); } display.clearDisplay(); display.setTextSize(2); display.setTextColor(SSD1306_WHITE); display.setCursor(10, 20); display.println("Dream RC!"); display.display(); } void loop() {}
If the display stays blank, change 0x3C to 0x3D on the I2C_ADDRESS line.
📊
Example 2 — Display Live Sensor Value (e.g. Temperature)
// Add after display setup in loop() — shows a live counter as example void loop() { float temperature = random(20, 40); // Replace with real sensor read display.clearDisplay(); // Label display.setTextSize(1); display.setTextColor(SSD1306_WHITE); display.setCursor(0, 0); display.println("Temperature:"); // Large value display.setTextSize(3); display.setCursor(0, 20); display.print(temperature, 1); display.println(" C"); display.display(); delay(1000); }
Replace the random() with your actual sensor read — e.g. DHT11, DHT22, or BMP280.
