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 cursor() and noCursor() methods to turn + on and off the cursor. + + 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) + + Library originally added 18 Apr 2008 + by David A.
