Hello, this is a great question that I can see has not been answered in full detail yet. Arduino is not a small community, but apparently there are not a lot of arduino savvy people that are trying to do this, though I am not quite sure why, considering they have thought of accomplished and done so many cool projects its uncomprehendable. I think we have hit a middle ground here, its probably not worth the time for many people on here, and I would imagine to most arduino enthusiasts this would be a walk in the park but they don't really know you are trying to figure it out, or we.. (did you ever nail it down? OP) I did see a couple of good ideas in here and some good 'hello world' advice, but 'hello world' is how I learned every language I know from the beginning, so seeing hello world is always a great start!
I'd like to add I used to use and mess with Arduino devices a few years ago for a while, it taught me how to write code in C++, well other than some Apache .htaccess stuff, but notheless I still own a few Arduino devices and am very interested in coming up with something that uses this and fully integrades it into some kind of guage sensor or similar. I have been using HWinfo 64 for as long as I can remember being on modern PC's that were powerful enough to have the need to monitor hardware, and I love it, and use it on all of my PCs.
I will find the answer to this, and I will share it if noone has figured it out or shared it otherwise. I signed up for an account here just for this purpose. Wish me luck.. lol..
Thanks!
