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.

This project utilizes an Arduino microcontroller along with an ultrasonic distance sensor to measure distances and provide warnings when objects are detected within certain ranges. The distance ...

Instead of measuring light, we measure the ambient voltage field on pin A5 and use it to detect if someone is too close to our Arduino. A5 is used as a “floating input”, but unfortunately it is very ...

Measure distance using an ultrasonic sensor and display it on the Serial Monitor. Ultrasonic Distance Measurement with Arduino This project demonstrates how to use an HC-SR04 ultrasonic sensor with an ...

This paper presents an experimental system that allows the study and testing of two proximity sensors (inductive and capacitive) and their use in an application. The guideline for studying these ...

It seems like engineering 101, but do you actually remember the specific differences between inductive proximity, inductive displacement, and eddy-current sensors? I asked a few friends and everyone ...

This letter presents an inductive sensor based on a micromachined coil for the detection of conductive targets. The proposed sensor consists of a planar micromachined sensing coil, a signal ...
