/* LiquidCrystalFast Library - Serial Input Demonstrates the use a 16x2 LCD display. The LiquidCrystalFast 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 displays text sent over the serial port (e.g. from the Serial Monitor) on an attached LCD. The circuit: * LCD RS pin to digital pin 12 * LCD WR pin to digital pin 10 * 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.
