That resulting signal is a square wave, which is an easy target for the Arduino to measure. That timing measured from the square wave can then be used to calculate the inductor’s value.

[Scott Daniels] takes a look at the other voltage measurement options available to AVR chips used by Arduino. If you’ve used the analogRead () function then you’ve already measured a voltage ...
