Cut and paste into your Arduino code environment. This code will light the LED connected to pin 13 (the one on your Arduino) when the button is pushed.

	NOTE: The circuit and code on the Arduino site really does not work very well. In the case of just turning on and off a led, it works ok, but having a floating low when the switch is pushed makes the circuit unreliable. To fix (Thanks Tim Knowles) we have the circuit default to low, then we pull the line high when the switch is pushed by engaging the internal resistor using this line of code...
