int ledPin = 13; // LED connected to digital pin 13
int inPin = 7;   // pushbutton connected to digital pin 7
int val = 0;     // variable to store the read value

void setup()
{
  pinMode(ledPin, OUTPUT);      // sets the digital pin 13 as output
  pinMode(inPin, INPUT);      // sets the digital pin 7 as input
}

void loop()
{
  val = digitalRead(inPin);   // read the input pin
  if (val == LOW) {            // judge the key state,the low is pressed
         digitalWrite(ledPin, HIGH);  //set the LED on and off
      } else {
         digitalWrite(ledPin, LOW);  //set the LED on and off
      }
}

Result

The light is off when the button is pressed and on when the button is released.
