how to use an LCD screen with Arduino

In this Arduino LCD Tutorial we will learn how to connect an LCD (Liquid Crystal Display) to the Arduino board. LCDs like these are very popular and broadly used in electronics projects as they are good for displaying information like sensors data from your project, and also they are very cheap.

#include <LiquidCrystal.h> // includes the LiquidCrystal Library 
LiquidCrystal lcd(1, 2, 4, 5, 6, 7); // Creates an LC object. Parameters: (rs, enable, d4, d5, d6, d7) 

void setup() { 
 lcd.begin(16,2); // Initializes the interface to the LCD screen, and specifies the dimensions (width and height) of the display } 
}

void loop() { 
 lcd.print("Arduino"); // Prints "Arduino" on the LCD 
 delay(3000); // 3 seconds delay 
 lcd.setCursor(2,1); // Sets the location at which subsequent text written to the LCD will be displayed 
 lcd.print("LCD Tutorial"); 
 delay(3000); 
 lcd.clear(); // Clears the display 
 lcd.blink(); //Displays the blinking LCD cursor 
 delay(4000); 
 lcd.setCursor(7,1); 
 delay(3000); 
 lcd.noBlink(); // Turns off the blinking LCD cursor 
 lcd.cursor(); // Displays an underscore (line) at the position to which the next character will be written 
 delay(4000); 
 lcd.noCursor(); // Hides the LCD cursor 
 lcd.clear(); // Clears the LCD screen 
}
