  2. LiquidCrystal Library - Autoscroll
  3. Demonstrates the use a 16x2 LCD display. The LiquidCrystal
  4. library works with all LCD displays that are compatible with the
  5. Hitachi HD44780 driver. There are many of them out there, and you
  6. can usually tell them by the 16-pin interface.
  7. This sketch demonstrates the use of the autoscroll()
  8. and noAutoscroll() functions to make new text scroll or not.
  9. The circuit:
  10. * LCD RS pin to digital pin 12
  11. * LCD Enable pin to digital pin 11
  12. * LCD D4 pin to digital pin 5
  13. * LCD D5 pin to digital pin 4
  14. * LCD D6 pin to digital pin 3
  15. * LCD D7 pin to digital pin 2
  16. * LCD R/W pin to ground
  17. * 10K resistor:
  18. * ends to +5V and ground
  19. * wiper to LCD VO pin (pin 3)
