        Reads the numeric code received by the `Infrared Receiver`_.

        :return: The numeric code of the symbol that was pressed on the `Infrared Remote`_.
        :rtype: int

        The numeric code represents the index of the :py:attr:`~easysensors.Remote.keycodes` list.
        By accessing the :py:attr:`~easysensors.Remote.keycodes` elements with the numeric code, you
        get the symbol that was pressed on the `Infrared Remote`_.

        For only getting the symbol that was pressed on the `Infrared Remote`_, please check the :py:meth:`~easysensors.Remote.get_remote_code` method.
