        Initialises a :py:class:`~di_sensors.easy_line_follower.EasyLineFollower` object and then returns it.

        :param str port = "I2C": The only option for this parameter for the `Line Follower Sensor (red board)`_ is ``"I2C"`` and for the `Line Follower Sensor (black board)`_ it can also be ``"AD1"``/``"AD2"``. The default value for this parameter is already set to ``"I2C"``.
        :returns: An instance of the :py:class:`~di_sensors.easy_line_follower.EasyLineFollower` class and with the port set to ``port``'s value.

        The ``"I2C"``, ``"AD1"`` and ``"AD2"`` ports are mapped to the following :ref:`hardware-ports-section`.

        .. tip::

             | The sensor can be connected to any of the I2C ports.
             | You can connect different I2C devices simultaneously provided that:

                * The I2C devices have different addresses.
                * The I2C devices are recognizeable by the `GoPiGo3`_ platform.

        The ``use_mutex`` parameter of the :py:meth:`~easygopigo3.EasyGoPiGo3.__init__` constructor is passed down to the constructor of :py:class:`~di_sensors.easy_line_follower.EasyLineFollower` class.
