>You'll be measuring possibly very small ceramics remember, so just just relying on the input impedance and capacitance of your microcontroller being negligible likely won't get you far
but that $8 meter project that is popular (but it is not $8 anymore) was originally running on some 8 bit micro and produced decent results measuring down to pf. no idea how they do that. but i am sure it is time constant based. that "arduino tester" is probably a spinoff of that project.
