How do I hook up multiple inputs to an arduino? And how do I use those in the programming? :-[
What sort of "inputs"? How many? What do you want to do with them?

As in 5 toggle switches and 1 pressure sensor.
Well, the toggle switches probably want to be connected between ground and a digital pin configured as an input with pull-ups (one pin per switch, don't use pins 0 or 1).
The pressure sensor could be analogue or digital, so without a spec, I'll decline to answer that one.
