 By default MicroPython sets the accelerometer range to +/- 2000 mg (``g`` being
 a unit of acceleration based on the standard gravity), which configures the

 The range can be changed via :func:`microbit.accelerometer.set_range`.
 
 The accelerometer also provides convenience functions for detecting gestures.
