Arduino Capmeter

LenP17 built a capacitor meter using the new Adafruit Arduino enclosure and LCD. The cap in question is placed in the sweet spot of a 555 circuit, and the resulting frequency is measured, correlated to a particular capacitance, and then displayed by the Arduino.

More info in the forums.

Nice work, Len!
