Tutorial Contents

Step 1: Physical Connection

LCD Module Pin outs

Connections :

• LCD pins 1,5, and 16 to the Ground
• LCD pins 2 and 15 to the VCC
• LCD pins 4,6,11,12,13 and 14 to digital pins of Arduino
• The middle pin of the Potentiometer to the LCD pin 3, others will be on VCC and Ground.

Step 2: Connection to IDE
Where to find the LiquidCrystal Library ?
go to Sketch > Include Library > then, find the LiquidCrystal Library.

and now, the library is on the sketch after clicking.

After that, you must select the board :
Open your IDE , go to Tools > Board > then choose Arduino/Genuino Mega or Mega 2560.

    LiquidCrystal lcd(1, 2, 4, 5, 6, 7); // Creates an LC object. Parameters: (rs, enable, d4, d5, d6, d7) 
    void setup() { 
     lcd.begin(16,2); // Initializes the interface to the LCD screen, and specifies the dimensions (width and height) of the display }

     delay(3000); // 3 seconds delay 
     lcd.setCursor(2,1); // Sets the location at which subsequent text written to the LCD will be displayed 
     lcd.print("LCD Tutorial"); 
     delay(3000);

     lcd.setCursor(7,1); 
     delay(3000); 
     lcd.noBlink(); // Turns off the blinking LCD cursor 
     lcd.cursor(); // Displays an underscore (line) at the position to which the next character will be written 
     delay(4000); 
     lcd.noCursor(); // Hides the LCD cursor 
     lcd.clear(); // Clears the LCD screen 
    }
