• Using a magnetometer can be a little tricky, especially if you are unsure about the formulas to use to get the correct bearing and when other magnetic objects are interfering with your signal. You could download a arduino library for this module, which will also be compatible with other HMC5883L breakout boards made by other manufacturers.
