The LiquidCrystal library allows you to control LCD displays that are compatible with the Hitachi HD44780 driver. There are many of them out there, and you can usually tell them by the 16-pin interface.

This example sketch shows how to use the setCursor() method to reposition the cursor. To move the cursor, just call setCursor() with a row and column position. For example, for a 2x16 display:

La librería LiquidCrystal te permite controlar displays LCD que sean complatibles con el driver Hitachi HD44780. Hay muchos de ellos ahí fuera, y puedes comunicarte con ellos a través del interfaz de 16 pines.

Este sketch de ejemplo muestra como usar el método setCursor() para reposicionar el cursor. Para mover el cursor, sólo llama a setCursor() con una posición de una fila y una columna. Por ejemplo, para un display de 2x16:

   LiquidCrystal Library - setCursor
  
  Demonstrates the use a 16x2 LCD display.  The LiquidCrystal
  library works with all LCD displays that are compatible with the 
  Hitachi HD44780 driver. There are many of them out there, and you
  can usually tell them by the 16-pin interface.
  
  This sketch prints to all the positions of the LCD using the
  setCursor(0 method:
  
   The circuit:
  * LCD RS pin to digital pin 12
  * LCD Enable pin to digital pin 11
  * LCD D4 pin to digital pin 5
  * LCD D5 pin to digital pin 4
  * LCD D6 pin to digital pin 3
  * LCD D7 pin to digital pin 2
  * 10K resistor:
  * ends to +5V and ground
  * wiper to LCD VO pin (pin 3)
