More and more keyboards and video game controllers employ Hall effect sensors, but what exactly is this technology? We break it down.

Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

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, an ...

The Hall sensors are read by an Arduino Nano, which computes the angles into movement of the pantograph head and records it as G-Code. This can simply be displayed on the attached LCD display, or ...

Hall-effect sensors can also be susceptible to magnetic interference, Mokhtari added, if they’re not properly shielded from magnets — which, by the way, Switch 2 Joy-Cons apparently use.
