LC Meter Using Arduino: Measuring Inductance and Frequency All embedded lovers are familiar with multimeter which a great tool to measure voltage, current, resistance etc. The connection of this circuit has a unique property of resonating at a precise frequency termed as the resonant frequency. When Lx or Cx is connected in the circuit the oscillator frequency will decrease and this decrease is measured by a frequency-voltage converter build with T3 and T4. For instance, both can store energy even though it is stored as a magnetic field by the inductor whereas a capacitor stores electric charge. Using this method we are able to calculate inductance about 80uH to 15,000uH, but it should work for inductors a bit smaller or much larger. As soon as the voltage on the LC circuit becomes positive, the LM339 will be floating, which can be pulled high with a pull up resistor. Like theirs, mine would measure the free running frequency of an LC oscillator, then successively apply a known capacitance then the unknown inductor (or capacitor).
