Using An Arduino and a LM339 Comparator To Measure an Unknown Inductance
/*
Inductance Meter Using Arduino - by J. Cantlin July 2, 2014
A coil of unknown inductance is connected in an LC crcuit. The
Arduino "rings" the circuit with a PWM pulse from a digital output.
The decaying sine wave from the LC circuit, i.e., tank circuit is
sent to an LM339 comparator where it is converted to a square
wave. The square wave is sent to the Arduino where the "pulseIN"
fuction reades its with in microseconds and converts it to the
resonant frequency of the LC circuit. With a known value of
