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 ...

Magnetic levitation technology enables objects to float by balancing magnetic forces and gravitational pull. This project focuses on constructing a magnetic levitation system using an Arduino, ...

This article describes how I have set up a simple “door-sentry” at home. The door-open detector is designed to alert you to an unauthorized entry in a confined area. It uses a little ATtiny85 ...

The magnet floating device operates using a small Hall Effect sensor where the field of the permanent magnet can be detected or be able to modulate the magnetic field of electromagnet. The magnet ...

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 ...
