/*LiquidCrystal Library - Hello World
Demonstrates the use a 16x2 LCD display. The LiquidCrystal
library works with all LCD displays that are compatible with the
Hitachi HD44780 driver. There are many of them out there, and you
can usually tell them by the 16-pin interface.
This sketch prints "Hello World!" to the LCD
and shows the time.
The circuit:
===============
LCD pin Connect to
----------
01 - GND GND, pot
02 - VCC +5V, pot
03 - Contrast Pot wiper
04 - RS Pin8 (P2.0)
05 - R/W GND
06 - EN Pin9 (P2.1)
07 - DB0 GND
08 - DB1 GND
09 - DB2 GND
10 - DB3 GND
11 - DB4 Pin10 (P2.2)
12 - DB5 Pin11 (P2.3)
13 - DB6 Pin12 (P2.4)
14 - DB7 Pin13 (P2.5)
15 - BL+ +5V
16 - BL- GND

// include the library code:
#include <LiquidCrystal.h>
// initialize the library with the numbers of the interface pins
LiquidCrystal lcd(P2_0, P2_1, P2_2, P2_3, P2_4, P2_5);
void setup() {
// set up the LCD's number of columns and rows:
lcd.begin(16, 2);
// Print a message to the LCD.
lcd.print("hello, world!");
}
void loop() {
// set the cursor to column 0, line 1
// (note: line 1 is the second row, since counting begins with 0):
lcd.setCursor(0, 1);
// print the number of seconds since reset:
lcd.print(millis()/1000);
