I'm currently working on a much more advanced project involving Arduino and VB.net. When i get a little further more source code will be made available.
Your code is nice. I'm planning on modifying it to use in my own project: 2 Arduino that will send temperature readings to the computer. I will be using XBee to send the data wireless.
