OLED I2C DISPLAY WITH ARDUINO Tutorial

Welcome guys Today we will Learn About OLED Display that is very easy and simple to learn. OLED I2C is a small type of display in that we can print a small amount of data in that. 

OLED I2C DISPLAY WITH ARDUINO Tutorial

Since this OLED works on I2C Communication, we have to connect

only 4 pins to Arduino

OLED has Sck (i.e. clock), SDA (i.e. Data) and Power pins i.e VCC and Ground.

On the Arduino UNO Board, we have SDA at A4 and SCK at A5.

Connections for OLED to Arduino

• Vcc - 5V
• Gnd - Gnd
• SDA - A4
• SCK - A5

• I2C Scanner

  

  

  we know each I2C device has a different Hexadecimal Address.

  since this OLED uses the I2C communication protocol, we have to find the I2C address for the display.

  #include < wire.h>

    Serial.begin (115200);

      }
    Serial.println ();
    Serial.println ("I2C scanner. Scanning ...");

    pinMode(13,OUTPUT); 
    digitalWrite(13,HIGH);
    Wire.begin();
    for (byte i = 1; i < 120; i++)
  void loop() {}

Code Parts

then Include these 4 Libraries in the header

#include <spi.h>
#include <wire.h>
#include <Adafruit_GFX.h>
#include <Adafruit_SSD1306.h>

#include<SPI.h>

#include<Wire.h>

#include<Adafruit_GFX.h>

#include<Adafruit_SSD1306.h>

#define OLED_RESET 4

Adafruit_SSD1306 display(OLED_RESET);

void setup() {

  // put your setup code here, to run once:

display.begin(SSD1306_SWITCHCAPVCC, 0x3C);

display.clearDisplay();

}

void loop() {

  // put your main code here, to run repeatedly:

display.setTextSize(1);

display.setTextColor(WHITE);

display.setCursor(0,0);

display.println("Welcome TO Home");

display.display();

}
