OLED display and Arduino

Hi Folks, today I am writing an article and this belongs to my video tutorial O-LED Display with Arduino on youtube. If this article helps you please subscribe to my youtube channel and like our Facebook page.
This article and video will teach you how to display the characters with Arduino. And you can find the Circuit Diagram and Arduino code below the page.

For this OLED Display with Arduino tutorial, I am using

  1. Arduino Uno
  2. Breadboard
  3. Some jumper wire
  4. OLED Display I2C 128/62

Video for a descriptive step-by-step guide for OLED Display with Arduino

Arduino Scanner Code to check I2C device

/*
CircuitMagic.com
*/
#include <Wire.h>
void setup()
{
  Wire.begin();

  Serial.begin(9600);
  Serial.println("\nI2C Scanner");
}
void loop()
{
  byte error, address;
  int nDevices;

  Serial.println("Scanning...");

  nDevices = 0;
  for(address = 1; address < 127; address++ ) 
  {
    // The i2c_scanner uses the return value of
    // the Write.endTransmisstion to see if
    // a device did acknowledge to the address.
    Wire.beginTransmission(address);
    error = Wire.endTransmission();

    if (error == 0)
    {
      Serial.print("I2C device found at address 0x");
      if (address<16) 
        Serial.print("0");
      Serial.print(address,HEX);
      Serial.println("  !");

      nDevices++;
    }
    else if (error==4) 
    {
      Serial.print("Unknow error at address 0x");
      if (address<16) 
        Serial.print("0");
      Serial.println(address,HEX);
    }    
  }
  if (nDevices == 0)
    Serial.println("No I2C devices found\n");
  else
    Serial.println("done\n");

  delay(5000); // wait 5 seconds for next scan
}

Now download the Adafruit_SSD1306 library from github.

    dont make full upload the proper code #incloude wire . h

  2. Vitalii Dereviankin 6 years ago

    #include is missing in the above code

  3. miguel 6 years ago

    #include “Wire.h”

  4. ArduinoElectroncis 5 years ago

    #include “Wire.h”

    Add Wire.h
