Gobetwino

Gobetwino is kind of a "genreric proxy" for Arduino. It's a program running on a PC (Windows only - sorry), that will act on behalf of Arduino and do some of the things that Arduino can't do on its own. So it works like a go between, hence the name.

Gobetwino is free, comes with a detailed user manual, and sample Arduino sketches to show how it can be used.

Gobetwino can bedownloaded here. Check this blog for information about updates, user suggestionns, and bugs.
