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 ...

Getting a magnetic field to balance on another magnetic field is about as easy as balancing a bowling ball on the tip of an ink pen. With a little help from an Arduino mega, however, [EmmaSong ...

Allegro MicroSystems’ surface-mount magnetic speed sensor contains a compensating circuit that reduces the detrimental effects of magnet and system offsets. “Digital processing of the analogue signal ...

The Scratch Duino programming is based on the Arduino platform and comes supplied with a variety of magnetic mounted sensors that can be installed and removed with ease. The Scratch Duino robot ...

Every week I seem to be writing about how someone has used an Arduino ... Hall effect sensor monitors the field of the permanent magnet and uses that information to modulate the magnetic field ...
