Arduino Tutorial: Read Button and Send Data to PC
/* Basic Digital Read
* ------------------
*
* turns on and off a light emitting diode(LED) connected to digital
* pin 13, when pressing a pushbutton attached to pin 7. It illustrates the
* concept of Active-Low, which consists in connecting buttons using a
* 1K to 10K pull-up resistor.

/* Sean Dockray added three lines to demonstrate sending button presses in to a PC! */
int ledPin = 13; // choose the pin for the LED
int inPin = 7; // choose the input pin (for a pushbutton)
