You usually need a high precision resistor (1% or better) in series with the inductor ... lets you pull it off with an Arduino and an LM339 quad comparator. The circuit works by feeding a signal ...

The reason why we talking again about them is that in this series of articles we are following a sort of plan: The aim is to give – all in the same place – suggestions which propose to the users ...

The end result is you can have the circuit simulator on the left of the screen and a Web-based Arduino IDE on the right side. But how does it work beyond the simple demo? We wanted to find out.

The series is the company’s most popular ... A microcontroller is a type of compact, power-efficient integrated circuit that can function as an Arduino’s chip primary onboard processor.
