8 | based on arduino LiquidCrystal Library |
||
9 | - scrollDisplayLeft() and scrollDisplayRight() |
||
10 | |||
11 | Demonstrates the use a 16x2 LCD display. The LiquidCrystal |
||
12 | library works with all LCD displays that are compatible with the |
||
13 | Hitachi HD44780 driver. There are many of them out there, and you |
||
14 | can usually tell them by the 16-pin interface. |
||
15 | |||
16 | This sketch prints "Hello World!" to the LCD and uses the |
||
17 | scrollDisplayLeft() and scrollDisplayRight() methods to scroll |
||
18 | the text. |
