“Many multi meters (like mine) don’t have the functionality of measuring capacitance. This is especially annoying as one has no way of determining how accurate a capacitor is. If you doubt your resistor you can easily measure it, but not so for the capacitor (if you have a multi meter like mine). So in this instructable I’m going to show you how to create a capacitance meter using an Attiny 85/45. This tester also has a 7 segment display to show the value.”
