+ 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.
