Help Getting Started with "Processing"

Using Arduino Programming Questions
1

How do I get an arduino to work hand in hand with "Processing" ? I see the project arduino code alongside a Processing script. how do I install the software to get the two programs to work? Do I need to add-on to the arduino 21 release or download another program?

Thanks

You can do it in two ways.

  1. Simply read and write from the arduino on the serial line with Serial.Print() and do the same at the processing end
  2. Load into the arduino some code called firmata, this makes the arduino into a dumb I/O module and use the arduino library from processing.
    I prefer 1) but 2) is easer (more simple minded and less flexible)
    See the communications part of:-

Here is what I am trying to do
