This module gives you access to the built-in electronic compass (mpu). The compass should be calibrated before use, otherwise the reading may be wrong.
note:The alignment compass causes the program to pause until the alignment is complete. Calibration consists of a small game, by rotating the board in the air to complete the circle calibration.
