Every week I seem to be writing about how someone has used an Arduino to fashion an interesting gadget, and today's – while not as obviously useful as, say a Pong-playing wristwatch - is still ...

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] was ...

[Photo: Joe Desbonnet] Have you ever wanted to find an inexpensive way of communicating with your Android phone wirelessly, but without relying on the likes of Bluetooth or Google ADK? If you also ...

The magnet floating device operates using a small Hall Effect sensor where the field of the permanent magnet can be detected or be able to modulate the magnetic field of electromagnet. The magnet ...

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 ...

We’re used to Hall effect devices as proximity sensors in mechanical systems, used to provide detection of something that has a magnet attached to it. However it’s easy to forget that the devices that ...

Makers, hobbyists and education establishments that have ever wanted to build their own robot, complete with a variety of different sensors. Are sure to be interested in a new open source robot called ...
