Capacitor Tester / Capacitance Meter

If, like myself, you’ve got an enormous stash of unlabelled electronic components that seem to look like capacitors, it’s probably a good idea to either throw them away or test them with a capacitance tester. Furthermore, there’s no need to go out and buy an expensive proprietary meter as the lowly Arduino will do a very good job just by adding a few resistors and using some clever coding.”
