Help with simple newbie project. Read resistance.

Ok, simple problem.. I have three buttons that are all fed 5v and each button has a different resistance value so I need a way of knowing WHICH button was pressed? For example purposes only, I want it to print to the serial which button was pressed. (1, 2, or 3)

Here is an example picture I made really quick to demonstrate what I mean:

Thank you! -Jason

you could connect each button to a different digital input pin

yeah, that's the one problem, though, is that I need it to stay on a single wire if at all possible. They are actually mounted on my steering wheel and I cannot run multiple wires through the clockspring.

Finally found a post that solved my problem!

Thanks anyways guys
