The Hall Magnetic Sensor project showcases how to use an Arduino Nano to detect a magnetic field with a Hall sensor. This project will light up an LED when a magnetic field is detected. It is useful ...

The Arduino Mega interfaces with a Hall magnetic sensor module to detect the presence and strength of magnetic fields, useful for applications such as proximity sensing, position detection, and motor ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

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 ...

[Dustin Andrews] built this add-on board which works as a proximity sensor. He wanted a standalone sensor for his Arduino projects which would use a single pin as a trigger. This lets him alert the ...

Low-dimensional magnetic heterostructures are a key element of spintronics, where magnetic interactions between different materials often define the functionality of devices. Although some interlayer ...
