I am trying to implement the following circuit through an Arduino
http://www.edn.com/design/component...-inductance?cid=Newsletter+-+EDN+Design+Ideas
Now basically I need to replace the ammeter and somehow measure the average current. Can anyone give me some methods to achieve this using an Arduino. I need accurate measurements as that value of average current will be proportional to the net inductance which I am trying to measure.
