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 ...

A Hall effect sensor or Hall sensor is a magnetic non-contact sensor that generates an electrical signal proportional to the magnetic field applied to it. Hall effect sensors are widely used in ...

There are plenty of PC joysticks out there, but that didn’t stop [dizekat] from building his own. Most joysticks measure position mechanically using potentiometers or encoders. Only a few high-end ...
