LiquidCrystal - blink() and noBlink()

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 blink() and noBlink() methods to blink a block-style cursor.

   LiquidCrystal Library - Blink
  
  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 makes the 
  cursor block blink.
  
  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)
