My project requires "some kind of remote communication to the PC" in order to work. It doesn't have to be wireless, wired is fine. The project is a desktop JAVA app that can either use the serial data, or use web data gotten via PUT and GET (see https://github.com/jjg/RESTduino
I've just priced all the available options: Ethernet shields, WiFi sheilds, XBee (which I could make work I think)...and it's all really just too expensive.
I need to keep the price of the finished project super super cheap.
Is there another way to get this done? I guess the short question is "what is the cheapest way to maintain comms between PC and the ardunio?"
I guess I could just use a super long USB cable and use the serial data? That seems ghetto though...there's got to be a cheap way to do ethernet?
