LiquidCrystal Library - Autoscroll LiquidCrystal Library - Autoscroll
Demonstrates the use a 16x2 LCD display. The LiquidCrystal Demonstrates the use a 16x2 LCD display. The LiquidCrystal
library works with all LCD displays that are compatible with the library works with all LCD displays that are compatible with the
Hitachi HD44780 driver. There are many of them out there, and you Hitachi HD44780 driver. There are many of them out there, and you

This sketch demonstrates the use of the autoscroll() This sketch demonstrates the use of the autoscroll()
and noAutoscroll() functions to make new text scroll or not. and noAutoscroll() functions to make new text scroll or not.
