LiquidCrystal Library - Increment/Decrement
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 demonstrates the use of the shiftIncrement()
and shifDecrement() functions.
The circuit:
* LCD RS pin to digital pin 12
* LCD Enable pin to digital pin 11
* LCD D4 pin to digital pin 5
* LCD D5 pin to digital pin 4
* LCD D6 pin to digital pin 3
* LCD D7 pin to digital pin 2
* 10K resistor:
* ends to +5V and ground
* wiper to LCD VO pin (pin 3)

// include the library code:
#include <LiquidCrystal.h>
// initialize the library with the numbers of the interface pins
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);
void setup() {
// set up the LCD's number of rows and columns:
lcd.begin(2, 16);
}
void loop() {
// set the cursor to (0,0):
lcd.setCursor(0, 0);
// set the display to left justify:
lcd.shiftDecrement();
// print from 0 to 9:
for (int thisChar = 0; thisChar < 10; thisChar++) {
lcd.print(thisChar);
delay(500);
}
// set the cursor to (16,0):
lcd.setCursor(16,1);
// set the display to left justify:
lcd.shiftIncrement();
// print from 0 to 9:
for (int thisChar = 0; thisChar < 10; thisChar++) {
lcd.print(thisChar);
delay(500);
}
// clear screen for the next loop:
lcd.clear();
