Easily measure inductance using Arduino

Posted on Thursday, July 21st, 2011 in Arduino, code, how-to, measurement by the machinegeek

Moser from ReiBot has developed a simple project for using an Arduino along with an LM399 and several discrete components to measure inductance. He says:

So you need to make or measure an inductor, but you don’t have an oscilloscope or signal generator? Measuring inductance with a handful of cheap common parts is certainly possible. I’ve verified this method is accurate with a scope from 80uH to 30,000uH, but it should work for inductors a bit smaller or much larger.

You can get more project details as well as the Arduino code (in a PDF) at ReiBot.org.

Via Adafruit.

    Gee, nice work!. I went to NIU too(Year 2005- student of Dr.Zinger). Go Huskies!

      Very cool! Dr. Zinger’s personality reminds me of a close friend I had at Huntington. I really look forward to NIU and *hopefully* getting to work in the clean room.

    I tried with two 0.1uF caps and with a 1mH inductance and it worked like a charm :) Thanks for sharing!

    A happy reader :)
