So here are all 3 prongs of the plane code thus far. This sends data to the visual basic program, then to the visual basic program where it gets interpreted and then sent to the plane simulator Arduino. Where it is written to servos and and led.

Just download those files and you should be able to open them in the vb studio.
Hey! This post was written a long time ago, but I'm leaving it up on the off-chance it may help someone. Proceed with caution. It may not be a good idea to blindly integrate this code or work into your project, but instead use it as a starting point.
Thanks for your post. I also believe that laptop computers have gotten more and more popular lately, and now tend to be the only kind of computer utilised in a household. Simply because at the same time potentially they are becoming more and more very affordable, their working power is growing to the point where they may be as effective as pc’s coming from just a few years ago.
Great post. I was checking constantly this blog and I am impressed! Very helpful info specially the last part 🙂 I care for such info much. I was looking for this particular info for a very long time. Thank you and best of luck.
