calls to some accelerometer method to do the gesture detection. Usually
gestures can be detected using a loop with a small :func:`microbit.sleep` delay.

.. py:function:: set_range(value)

Set the accelerometer sensitivity range, in g (standard gravity), to the
closest values supported by the hardware, so it rounds to either ``1``,
``2``, ``4``, or ``8`` g.
