As promised in the January Nuts&Volts Smiley's Workshop 18 - Serial Communications Part 1 - Graphical User Interfaces this is the thread to ask questions about that article.
If you are new to AVRFreaks PLEASE read:
Newbie? Start Here!
I'm starting this special thread to handle questions about the article since it involves the Arduino, and .NET Express - two topics that are almost guaranteed to get some of the more flammable denizens of AVRFreaks over-excited, therefore to protect the innocent I'll check several times a week (for a while) to see if any of the Nuts&Volts readers have any questions or if any of the AVRFreak denizens need to be hosed off.
BTW this is all AVR related, the source code is free and I'll even post the article for free one month after it runs in Nuts&Volts.
