Pic Basic has a analogue to digital converter

Yes I have used a Pic before, only the basics.

Do you already have a PIC chip model in mind??
Are you targeting a specific pin count or just wanting to experiment with A/D?

As far as feeding the A/D value to a PC via USB, I have not done that (others here have I'm sure) but you could easily write that value to an LCD or other display or feed it to a PC via serial.

Some more specifics on what your overall goal is might help.

Any Pic chip would do and just any number of pins would be fine.

Thanks
