another serial prob

hi i got this problem with this sketch:
it keeps doinig nothing. its supposed to print "HelloWorld" when the button was pressed. and "Nothink to see here" when nothink happens...

int sw = 3;

void setup(){                   
Serial.begin(9600);
pinMode(sw, INPUT);
}

void loop()
{
  if (sw == LOW) {
 Serial.print ("HelloWorld");
  }
  if (sw ==HIGH) {
 Serial.println("Nothink to see here");
  }
}

any help is appreciated :stuck_out_tongue:

You're not reading the state of the pin "sw" anywhere.

you need a "digitalRead" in your "loop()"

The value of "sw" is always three, and therefore neither "HIGH" (1) nor "LOW" (0), so nothing ever gets printed.
