  LiquidCrystal Library - Autoscroll
 | 
			
		||||
 
 | 
			
		||||
 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 demonstrates the use of the autoscroll()
 | 
			
		||||
 and noAutoscroll() functions to make new text scroll or not.
 | 
			
		||||
 
 | 
			
		||||
 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)

  LiquidCrystal Library - Serial Input
 | 
			
		||||
 
 | 
			
		||||
 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 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 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)
