/* 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 pin Connect to --------------------------------- 01 - GND GND, pot 02 - VCC +5V, pot 03 - Contrast Pot wiper 04 - RS Pin8 (P2.0) 05 - R/W GND 06 - EN Pin9 (P2.1) 07 - DB0 GND 08 - DB1 GND 09 - DB2 GND 10 - DB3 GND 11 - DB4 Pin10 (P2.2) 12 - DB5 Pin11 (P2.3) 13 - DB6 Pin12 (P2.4) 14 - DB7 Pin13 (P2.5) 15 - BL+ +5V 16 - BL- GND ================================= Library originally added 18 Apr 2008 by David A.
