  ShiftLCD Library - Scroll
 
 Demonstrates the use a 16x2 LCD display.  The ShiftLCD 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
 scrollDisplayLeft() and scrollDisplayRight() methods to scroll
 the text.
 
  The circuit:
 
 ---Shift Register 74HC595---
 * SR Pin 14 to Arduino pin 2
 * SR Pin 12 to Arduino pin 3
 * SR Pin 11 to Arduino pin 4
 * SR Pin  8 to Ground
 * SR Pin 16 to +5v
 * SR Pin 13 to Ground
 * SR Pin 10 to +5v
 -----Shift Reg to LCD--------
 * SR Pin 15 to D7
 * SR Pin 1  to D6
 * SR Pin 2  to D5
 * SR Pin 3  to D4
 * SR Pin 5  to MOSFET gate
 * SR Pin 6  to Enable
 * SR Pin 7  to RS
 -----LCD HD44780-------------
 * Vss to Ground
 * Vdd to +5V
 * Vo  to 10k Wiper
 * R/W to Ground
 * 5v  to +5v
 * Gnd to MOSFET Drain
 ------N Chanel MOSFET--------
 * Source to Ground
 * Gate   to SP Pin 5
 * Drain  to LCD Gnd
 * 1k Resistor Between gate and source

}

  // scroll 27 positions (display length + string length) to the left:
  for (int positionCounter = 0; positionCounter < 27; positionCounter++) {
    // scroll one position left:

    delay(200);
  }

  // scroll 27 positions (display length + string length) to the right:

    // scroll one position right:
