I am an experienced arduino user but have absolutely no experience (or knowledge of) Processing. I just downloaded the windows version here. http://processing.org/
and tried to follow these instructions:
Unzip the library and copy the "arduino" folder into the "libraries" sub-folder of your Processing Sketchbook. (You can find the location of your Sketchbook by opening the Processing Preferences. If you haven't made a "libraries" sub-folder, create one.) Run Arduino, open the Examples > Firmata > StandardFirmata sketch, and upload it to the Arduino board.
I was unable to follow THIS instruction:
Run Arduino, open the Examples > Firmata > StandardFirmata sketch, and upload it to the Arduino board.
because there is no "Firmata" in any Examples menu that I can find. In fact, I can't find "Firmata " anywhere. I found this page but can't find I googled it and found this: http://firmata.org/wiki/Main_Page
but can't find any instructions on how to use it. At this point I don't know if I need something else. I unzipped the Firmata archive and copied the "arduino " folder into my C:\My Documents\Arduino\Libraries" folder and it created a bunch of folders there but there was nothing like a Readme file so I have no idea how to get it working. I would appreciate some help figuring out how to use Processing.
