* This sketch demonstrates the use of a simple Hall Effect sensor. * The sensor works like a button. When a magnet is near it, the sensor * closes and the LED on Pin 13 turns on. * This sketch was ...

The Arduino Uno Hall Magnetic Sensor detects magnetic fields and changes in magnetic polarity. It utilizes the Hall effect to produce a voltage proportional to the magnetic field strength, enabling ...

Need a Hall sensor? A strip of copper, a strong magnet, and an LM358 are all you need to explore the Hall effect hands-on. This experimental setup turns microvolt signals into measurable millivolt ...
