Today I continued off from last time where I worked on making a button that would allow one to set the Arduino port directly from Ardublock instead of using the Arduino menu. I did a bunch of internet searching, and found a website with a Java-Arduino interaction library with methods that would allow me to achieve this goal. I started to write some code in a PortButtonListener.java file, but my Java knowledge is a little rusty, so I'll probably have to troubleshoot it quite a bit before it starts working. 

I'm a little confused on how I would create a new instance of the downloaded Arduino class, and how I would be able to get the port description, but I'll work on being able to do so.
