Circuit Diagram

Follow the circuit diagram for making connection. I make this circuit in Easy EDA software.

Follow the Circuit Connection :-

LCD RS pin to digital pin 12
LCD Enable pin to digital pin 11
LCD D4 pin to digital pin 6
LCD D5 pin to digital pin 5
LCD D6 pin to digital pin 4
LCD D7 pin to digital pin 3
LCD R/W pin to ground
LCD VSS pin to ground
LCD VCC pin to 5V Connect
10K variable resistor (POT) :-

First to +5V and ground
Second to LCD VO pin (pin 3)
Last to GND

Code

Arduino Code

C/C++
Simply Copy the following code & upload in your Arduino IDE software.
/*
  Hello friends welcome to "TECHNO-E-SOLUTION"
  Here, is a code to interface LCD with Arduino
*/

#include <LiquidCrystal.h>

const int rs = 12, en = 11, d4 = 6, d5 = 5, d6 = 4, d7 = 3;
LiquidCrystal lcd(rs, en, d4, d5, d6, d7);

void setup() {
  
  lcd.begin(16, 2);  // set up the LCD's number of columns and rows:
  
  lcd.print("   16 X 2 LCD   ");  // Print a text to the LCD.
}

void loop() {
  
  lcd.setCursor(0, 1);  // set the cursor to column 0, line 1
  lcd.print(" LCD + ARDUINO  ");
}
