Interfacing lcd 16x2 with Arduino

Liquid Crystal Display:

                 A liquid-crystal display (LCD) is a flat-panel display or other electronically modulated optical device that uses the light-modulating properties of liquid crystals. Liquid crystals do not emit light directly, instead using a backlight or reflector to produce images in color or monochrome.

          16 represents number of columns and 2 represents number of rows.

                

Pin Description:

Hardware Required:

•  Arduino &USB cable
•  16X2 LCD
•  Bread Board
•  Connecting Wires

Connections:

Arduino program to print Hello World!:

	#include <LiquidCrystal.h>
	// initialize the library by associating any needed LCD interface pin
	// with the arduino pin number it is connected to
	const int rs = 12, en = 11, d4 = 5, d5 = 4, d6 = 3, d7 = 2;
	LiquidCrystal lcd(rs, en, d4, d5, d6, d7);
	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!");
	}
