Beginner here
I've built a three gate RC oscillator from a 74AHC04 with the capacitor interchangeable to test random capacitors as a learning experience.

I've got an Arduino set up reading the frequency (perhaps a capacitance meter build?) but I have no clue how to solve for the capacitance.

I've googled like a mad man but I can only find ready made calculators for it or how to calculate the frequency from the resistor(s) and the capacitor but not capacitor from frequency and resistor, and I am horribad at math.

Anyone that can point me in the right direction, please?
