[mircemk] shows how to create a simple non-contact proximity sensor using little more than an Arduino Nano board, and a convenient software library intended to measure the value of capacitors. The ...

I needed a tacho/RPM display for a CNC spindle. I decided to use an Arduino Micro and OLED display with a reflective LED/Photo transistor as a sensor. Since powering up, a clock can display the total ...

This simple device, built using an Arduino Nano and an A3144 Hall sensor, allows you to measure the RPM (Revolutions Per Minute) of a gear. The device is straightforward to construct and program, ...

Inductive position-measuring systems (IPMSs) operate on the same principle as an inductive proximity sensor. But instead of a single sensing coil, position measuring uses a multiple-coil system ...

Abstract: Accurate measurement of fabric dimensions is essential for productivity and quality in the textile finishing industry. Traditional manual methods, such as measuring tapes, are often ...
