LCD 16x2 Showing no text
After a bit of contrast adjustment the photo show pin 3 is connected:



But as others have commented the Original Poster needs to edit the question to add more details about what has been connected to what and example code that proves that when the controller code changes a signal that change reaches the LCD module.

EDIT

Sanjeev,

This is the Arduino sketch I got to work:

#include &lt;LiquidCrystal.h&gt;

LiquidCrystal lcd(1, 2, 4, 5, 6, 7);

void setup() {
    lcd.begin(16,2);
}

void loop() {
    lcd.print("Sanjeev");
    delay(3000);
    lcd.setCursor(2,1);
    lcd.print("LCD is working");
    delay(3000);
    lcd.clear();
    lcd.blink();
    delay(4000);
    lcd.setCursor(7,1);
    delay(3000);
    lcd.noBlink();
    lcd.cursor();
    delay(4000);
    lcd.noCursor();
    lcd.clear();
}


This is how I connected my Arduino UNO:



This is it running:

@sanjeev-sharma, From your photos it looks like you have reversed the order of the data bit lines from the Arduino to the LCD module.
