 Input Pullup Serial

 This example demonstrates the use of pinMode(INPUT_PULLUP). It reads a
 digital input on pin 2 and prints the results to the serial monitor.

 The circuit:
 * Momentary switch attached from pin 2 to ground
 * Built-in LED on pin 13

 Unlike pinMode(INPUT), there is no pull-down resistor necessary. An internal
 20K-ohm resistor is pulled to 5V. This configuration causes the input to
 read HIGH when the switch is open, and LOW when it is closed.
