/*
  Graph

  A simple example of communication from the Launchpad to the computer:
  the value of analog input 0 is sent out the serial port. We call this "serial"
  communication because the connection appears to both the Launchpad and the
  computer as a serial port, even though it may actually use
  a USB cable. Bytes are sent one after another (serially) from the Launchpad
  to the computer.

  You can use the Energia serial monitor to view the sent data, or it can
  be read by Processing or another program capable of reading
  data from a serial port. The Processing code below graphs the data received
  so you can see the value of the analog input changing over time.

  The circuit:
  Any analog input sensor can be attached to an analog pin.
  For this example, a potentiometer is attached to analog pin 3.
