Handy capacitance tester on Arduino

If you are working on capacitance sensitive projects, it is recommended to check capacitor value before use. Practically any multimeter already have capacitance measure mode. If you are not satisfied with its range or want to have dedicated device, consider of building one. Braulio777 have written pretty illustrative instructable where he shares all building steps on how he built cap meter. It is capable of measuring capacitance from 0.000pF 0.001pF to 1000uF.

The meter is built around Arduino where external components are assembled on separate Arduino proto shield with 16×2 LCD on top. He run several tests that prove that meter works within specs. With enclosure and battery it becomes decent portable meter.
