Code Shield Hall Sensor Test and Demo

The Hall effect sensor is an analog sensor that allows us to read the strength and polarity of the a magnetic field. This sketch uses the serial monitor to output sensor data.

/* Diyode CodeShield Hall sensor

the hall sensor is sensitive to maagnetic fields and polarity

run this sketch and watch the serial monitor.

bring a magnet close to the sensor and watch the change on serial

monitor.

turn the magnet so the other pole is facing the sensor

observe the change in the serial monitor
