Intro: Temperature Sensor(LM35) With LCD(JHD162A)

Hey guys!
moxigen here. Since the summer's out here it's been scorching hot and has made me wonder what would be the temperature. Hence, I decided to put together some stuff to create a temperature sensor.

Step 1: Materials Required

You would require the following parts:
1. A 16x2 LCD screen(JHD162A used in my case.

2. A 10k potentiometer.

3. LM35 temperature sensor

4. jumper wires

5.A breadboard

6. A Arduino Prototype( Arduino Mega 2560 used in my case)

Step 2: Wire It Up

Connect the LCD and LM35 as shown.

Step 3: Uploading the Code Via USB

#include
float temp;
int tempPin = 0;
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

void setup()
{
  Serial.begin(9600);
  lcd.begin(16, 2);
}

void loop()
{
  temp = analogRead(tempPin);
  temp = temp * 0.48828125;
  Serial.print("TEMPRATURE = ");
  Serial.print(temp);
  Serial.print("*C");
  Serial.println();
  lcd.setCursor(0,0);
  lcd.print("Temperature:");
  lcd.setCursor(0,1);
  lcd.print(temp);
  lcd.print("*c");
  delay(1000);
}

Step 4: Acknowledgements

Thank ya all for having a look at my instructable. I'm open to criticism, so feel free to comment.

    Please recheck which temperature sensor model you're using and check the wiring.

    I'll have the code forwarded to you, I've already done that project.
    For assembling the stuff, check out my other instructable in which I've used 2 seven segment displays.

    Yo! Buddy I'm Ritik....I'm Also 15. Well this is a nice instructable...Really enjoyed it.

    But you could have used Backlight for the LCD,that would have looked very nice.

    @RitikBharadwaj
    connect the last pin on the right to GND and the 2nd last one to 3.3v(no resistor required) and the backlight would be on. I have shown it in my 3rd fritzing diagram.
