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 ...

and as a tribute [Ben North and Oliver Nash] have created a 32-bit magnetic core memory board for the Arduino. Magnetic core memory was used from the 1950s through the 1970s, and provided a non ...

with everything being crunched by the Arduino. It's basically keeping the magnet dangling by pulling it upward at varying rates, changing the power according to the changing magnetic field.

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 ...

Whether you want to duplicate your easily losable keycard or you want to duplicate other magnetic card stripes, you can do so with just an Arduino, some electrical tape, copper wire, and a thin ...

An additional Electro-Magnetic Relay (EMR) is also attached to the interface circuit. With the help of this relay, it is easy to energize other (external) high-power blinkers or beepers, if necessary.

Microduino’s new generation of little stackable Arduino modules, mCookie, is both magnetic and Lego-compatible. If you thought you could do everything with Legos before, well, you were pretty ...

Fancy making a cool looking magnetic levitating lamp? Check out this Arduino Nano-based project that combines a magnet and LEDs. What's that you say? The lamp is not levitating, it's being held up?
