I am trying to build an LC meter using the Arduino platform. It's based on this tutorial here.
Specification: 10nH to 1000nH, 1uH to 1000uH, 1mH to 100mH and capacitance from 0.1pF up to 900nF.
However, I am unsure which prescaler to use for the timer. If I'm not mistaken the timer affects how accurately the frequency is measured, thereby affecting the measured inductance /capacitance. How can I choose a suitable one?
