Examples
The magnetometer is typically read in the reading
event
callback. In the example below this occurs sixty times a second.
let magSensor = new Magnetometer({frequency: 60});
magSensor.addEventListener('reading', e => {
console.log("Magnetic field along the X-axis " + magSensor.x);
console.log("Magnetic field along the Y-axis " + magSensor.y);
console.log("Magnetic field along the Z-axis " + magSensor.z);
});
magSensor.start();
