LCD display







The use a 16x2 LCD display.  The Liquid Crystal library works with all LCD displays that are compatible with the Hitachi HD44780 driver. This code prints "Hello World!" to the LCD

 Connections

 * 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

 * LCD R/W pin to ground

 * LCD VSS pin to ground

 * LCD VCC pin to 5V

 * 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 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);

}
