LiquidCrystal - display() and noDisplay()

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 display() and noDisplay() methods to turn on and off the display. The text to be displayed will still be preserved when you use noDisplay() so it's a quick way to blank the display without losing everything on it.

LiquidCrystal - display() y noDisplay()

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 los métodos display() y noDisplay() para encender y apagar el display. El texto a mostrar se preservará cuando uses noDisplay() por lo que es la forma más rápida de limpiar el display sin perderlo todo.

   LiquidCrystal Library - display() and noDisplay()
  
  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 "Hello World!" to the LCD and uses the 
  display() and noDisplay() functions to turn on and off
  the display.
  
  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)
