There are many articles about measuring capacitance using an Arduino. In the simplest form they just measure the time to charge or discharge the capacitor with known voltage through a resistor. But some are elegant, requiring no additional components at all!. This concept seems a little ridiculous, but see the articles on Codewrite.co.uk by Jonathan Nethercott, linked to in the references section below. With a bit of inspired thinking and ideas from others an elegant solution to capacitance measurement was born.

To test out the viability of this approach I constructed a basic implementation using an Arduino

Here is my initial program using Jonathan's code and a driver for a serial LCD : Initial capacitor meter code for Arduino UNO and KS0073 display.
