Project 6: Geomagnetic Sensor

(1) Project Introduction
This project aims to explain the use of the Micro: bit geomagnetic sensor,
which can not only detect the strength of the geomagnetic field, but also
be used as a compass to find bearings. It is also an important part of the
Attitude and Heading Reference System (AHRS).
