So after hours and hours of prodding the Arduino site, and coming up with half the information by using google (which points me back to the arduino site at a place I never found before) I've managed to learn a few more things about the process...I think.

So Arduino calls a program running on the Duemilanove a "Sketch", correct? One can create Sketches by using cross platform software for free, and it is written in a "C like" language.

So, let's say I've wired my Duemilanove to my analog inputs, I've got a proper Sketch program running on the Duemilanove that converts and forwards that analog input to the USB connected to a computer. At this point I can not figure out what the process is programatically for accessing the information coming from the Duemilanove. And if I can't figure out the process, I don't know how easy/hard it is, or if it's possible on my chosen platform.

Thoughts?

The 4th year CS student and knowing everything was kind of a joke... I'm pretty sure as seniors we are aware we know even less, than we are aware of when we started as freshmen.
In fact undergrad seems to be about finding out about all the areas you know jack shiet about, and then moving on smiley-wink

But anyway!

I would love to use the board for all kinds of things, as I love exploring and learning. The major set of analog inputs in my life, and ones I can play around with mathematically with ease, are the analog inputs to the instrument cluster in my old car. So in other words, I believe 8 bits should be plenty. 100mph/1024 is probably more accurate than the instrumentation! smiley

So the voltage I am reading will be constant...or fluid... or some other good EE term for non-spiking input.

Though this does bring up a point. If I were trying to pick up a single timed signal volt, say the voltage required to open a fuel injector, is there a frequency that would max out the ability of the board to detect?

So to break it down, here is what I'm understanding so far.
If I go with the Duemilanova I will have the following steps:

1. program the Duemilanova to map the analog inputs to the USB. Is that sufficient? Seems like relatively simple code if all I want is the ADC functionality.

2. Write code on whatever platform I like, to read in the data coming from the USB port. At this point we are out of the hands of Arduino, right? Or are their supporting drivers that are required?

Thanks for all your input so far!

So, to start off, I'm a computer science student in his senior year, so I know everything about code, and nothing about electronics :-)

I want to read a bunch of analog signals(3 to 6) that are 0-5v, or 0-1v, and bring them into my computer and access that information using C#/Java or whatever.

Which product might you all suggest? And what is the learning curve required? I've done some reading, but I'm lacking a large base knowledge to fully comprehend what it is I'm getting myself into smiley-sad
