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 ...

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 ...

The Arduino magnetic drawing machine operates using an Arduino board mounted with a magnetometer. This setup, combined with node.js and socket.io, allows the machine to detect disturbances in the ...

Joe Desbonnet combined an Arduino microcontroller with a magnetic coil to create what he calls the “Poor Man’s NFC”. The hack allows for a one-direction, low-bandwidth connection between an ...

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 ...

Using an Arduino, a Hall effect sensor and an electromagnet, the microprocessor board can keep a floating magnet perfectly positioned.Video demos after the cut The Hall effect sensor monitors the ...
