/*
To interface a 16x2 LCD with Arduino, you can use the LiquidCrystal library. Here's a simple example:

RS => Arduino Pin 7
EN => Arduino Pin 8
D4 => Arduino Pin 9
D5 => Arduino Pin 10
D6 => Arduino Pin 11
D7 => Arduino Pin 12
*/

#include <LiquidCrystal.h>

// Initialize the LCD and specify the GPIO pins
LiquidCrystal lcd(7, 8, 9, 10, 11, 12);

void setup() {
  // Set up the LCD's number of columns and rows:
  lcd.begin(16, 2);

  // Print a message to the LCD
  lcd.setCursor(0, 0); 
  lcd.print("Hello, world!");
  lcd.setCursor(0, 1);
  lcd.print("Arduino");
}

void loop() {
  // No need to repeat anything in the loop for this simple example
}
