  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
   LCD R/W pin to ground
   10K resistor:
   ends to +5V and ground
   wiper to LCD VO pin (pin 3)

  // set up the LCD's number of columns and rows:

  {
    lcd.scrollDisplayLeft(); //Scrolls the contents of the display one space to the left.
    lcd.print("<-- -->"); // Print a message to the LCD.
    delay(500); //wait for 250 microseconds
  }

  lcd.clear(); //Clears the LCD screen and positions the cursor in the upper-left corner.
