Arduino LCD Connection. LCD not displaying anything

[Deepak]

Used Pin Connection:

LCD Pin to  Arduino Pin

14 to Arduino 2 

13 to Arduino 3

12 to Arduino 4 

11 to Arduino 5

6 to Arduino 10 

5 to Arduino 11

4 to Arduino 12

1 to Arduino GND

2 to Arduino +5V

Used the Code:

// include the library code:

#include // 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(" Chakk Do fatte"); lcd.setCursor(0, 1); lcd.print("Balle Balle"); } void loop() { //TO CHANGE the text of the display, find the following values : lcd.print(" **Text for line 1 of LCD**"); lcd.print(" **Text for line 2 of LCD**"); }

 

 

The Problem is: Nothing is displaying!
