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 Nano magnetic sensor detects magnetic fields and provides output proportional to their strength. It's used for applications like proximity sensing, position detection, and compass ...

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 ...

Hello everyone! Today I’m going to discuss a cheap type of useful digital rotation per minute counter (Digital RPM Counter). The 4-Digit LED Display RPM comes with a magnetic proximity sensor switch.

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 ...
