Simple to use Arduino library to interface to HMC5883L Magnetometer (Digital Compass) This library makes getting a compass heading from an HMC5883L Magnetometer very simple, it includes adjustment for ...

We don’t have much personal experience with DOF hardware, but this Arduino library which reads and compensates for three-axis magnetometer and accelerometer data looks very impressive. It sho… ...

The build uses a HMC5883L magnetometer. While this can detect magnetic fields in three axes, just one is necessary for building a device that operates akin to a traditional compass.
