How to use a 16x2 lcd display with Arduino

So today I will tell you how to use the 16x2 LCD display on the Arduino projects. If you are doing any kind of projects then you should interact with the user in the simplest process.To add any kind of output device is the key to simplify that project. you may show the options or the compilation details using that. 

There various types of displays available in the market but among them the 16x2 LCD display is the famous and cheapest one.As it has a very simple process to implement them in the projects.

pinout for the 16x2 LCD display:

Test code to check the connection is properly done or not:

/*

  LiquidCrystal Library - Test code

  #DNY

 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.

  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

 * 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 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("congrats!");

}

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("Done; #DNY ");
