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 ...

The microcontroller of choice for this project was the Arduino UNO R3. Maybe be modified in the future to work with the TM4C123G launchpad. References two GitHub repositories created by Andrew ...

This library was written based on the rotation detection method described @ https://youtu.be/atb6d4b-VYk and also in the pdf included with the library, so if you ...

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 ...

What is a rotary encoder? A rotary encoder (RT) is a device that you can rotate infinitely. On most rotary encoders, when you rotate them you will feel a bump (known as steps), and most RTs have about ...

The project is based around the AS5040 chip that uses a magnet to provide positional feedback information and 10 bits of resolution per rotation. The project is based around the AS5040 chip that uses ...

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 ...
