[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.

It’s something [mircemk] demonstrates, with an Arduino-powered magnetic field strength meter that uses a UGN 3503U Hall effect device. The circuit is extremely simple, comprising the sensor ...

With their cheap price tags, massive I/O provisions, and low power consumption, microcontrollers like the uber-popular Arduino family have diverse use cases, from simple automation projects to ...
