2 LiquidCrystal Library - Serial Input
4 Demonstrates the use a 16x2 LCD display. The LiquidCrystal
5 library works with all LCD displays that are compatible with the
6 Hitachi HD44780 driver. There are many of them out there, and you
7 can usually tell them by the 16-pin interface.
9 This sketch displays text sent over the serial port
10 (e.g. from the Serial Monitor) on an attached LCD.
