| 8 | based on arduino LiquidCrystal Library - TextDirection |
||
| 9 | |||
| 10 | Demonstrates the use a 16x2 LCD display. The LiquidCrystal |
||
| 11 | library works with all LCD displays that are compatible with the |
||
| 12 | Hitachi HD44780 driver. There are many of them out there, and you |
||
| 13 | can usually tell them by the 16-pin interface. |
||
| 14 | |||
| 15 | This sketch demonstrates how to use leftToRight() and rightToLeft() |
||
| 16 | to move the cursor. |
