LCD I2C Arduino Setup

0:31

Aquí tienes el código actualizado para tu LCD 16×2 con módulo I2C, agregando también la librería LiquidCrystal para compatibilidad (aunque en este ejemplo se utiliza LiquidCrystal_I2C para la comunicación I2C):

Cpp
#include 
#include 
#include   // Librería adicional para pantallas LCD sin I2C

// Configuración para LCD con módulo I2C: dirección 0x27, 16 columnas y 2 filas
LiquidCrystal_I2C lcd(0x27, 16, 2);

void setup() {
  // Inicializa el LCD y activa la retroiluminación
  lcd.init();
  lcd.backlight();
  
  // Muestra el mensaje en el LCD
  lcd.clear();
  lcd.setCursor(0, 0);
  lcd.print("LA CAVERNA DE");
  lcd.setCursor(0, 1);
  lcd.print("PLATON");
}

void loop() {
  // No se requiere código en loop para este ejemplo
}

Nota:
Aunque se ha incluido la librería LiquidCrystal, en este ejemplo se utiliza LiquidCrystal_I2C para la comunicación mediante I2C. Si en algún futuro deseas utilizar una pantalla LCD sin el módulo I2C, deberás conectar más pines (al menos RS, E, D4-D7) y utilizar la instancia de la clase LiquidCrystal en lugar de LiquidCrystal_I2C.
