• 0.96" 128x64 OLED Display Module (7-pin, I2C)
• Arduino (Uno, Nano, or any 5V/3.3V-compatible board)
• Jumper wires
• Breadboard (optional)
• 4.7kΩ resistors (for I2C pull-up resistors, optional but recommended)

1. GND - Ground (Connect to the ground of your microcontroller)
2. VCC - Power supply (3.3V or 5V, depending on your microcontroller)
3. D0 (SCL) - I2C Clock Line (SCL)
4. D1 (SDA) - I2C Data Line (SDA)
5. RES - Reset pin
6. DC - Data/Command control pin
7. CS - Chip Select (for SPI, not needed for I2C)

1. Open the Arduino IDE and go to Sketch > Include Library > Manage Libraries.
2. In the Library Manager, search for "Adafruit SSD1306" and click "Install."
3. Search for "Adafruit GFX" and install that as well.

cpp
Copy code#include <Wire.h>
#include <Adafruit_GFX.h>
#include <Adafruit_SSD1306.h>

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

// Reset pin for the display
#define OLED_RESET 4
Adafruit_SSD1306 display(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, OLED_RESET);

void setup() {
  // Initialize serial communication for debugging
  Serial.begin(9600);

  // Initialize the OLED display
  if (!display.begin(SSD1306_I2C_ADDRESS, OLED_RESET)) {
    Serial.println(F("SSD1306 allocation failed"));
    for (;;); // Don't proceed, loop forever
  }

  // Clear the buffer
  display.clearDisplay();
  
  // Display text
  display.setTextSize(1);
  display.setTextColor(SSD1306_WHITE);
  display.setCursor(0,0);
  display.println("Hello, OLED!");
  display.display();
}

void loop() {
  // You can add more code here for dynamic content
}

1. Connect your Arduino to your computer via USB.
2. Copy and paste the example code into the Arduino IDE.
3. Select the correct board and port under Tools > Board and Tools > Port.
4. Click Upload.

• No display: Double-check wiring, especially the power and I2C connections (SCL and SDA).
• Flickering or random behavior: Ensure proper pull-up resistors on the I2C lines if your microcontroller doesn’t have internal ones. Use 4.7kΩ resistors from the SCL and SDA lines to VCC.
• OLED not initializing: Verify that the correct reset pin is defined in the code (OLED_RESET pin).
