Step 9A word on Wireless
One thing I haven't talked about yet, is how the wireless communication is being achieved. I am using xBee wireless modems. xBee's are an easy way to make a wireless point-to-point connection, or create a mesh network. To interface with my Arduino board, I used LadyAda's xBee adapter. It's inexpensive, easy to put together and there is a detailed instructional website explaining how to configure it.
Through a combination of this website, and a chapter on xBee radio's in the book "Making Things Talk" (Tom Igoe), I implemented, possibly what is the simplest use of these radios, which are actually quite powerful.
I got my adapters and xBees (+ the appropriate cable) from here.
Instructions on configuring the xBees are here.
The only thing i'm not going into is how to configure the xBees. I did it very easily (on a mac) by transcribing some code from Igoe's book that uses Processing to create a simple terminal for programming the xBee. That code is on page 198.
