/***
    eeprom_put example.

    This shows how to use the EEPROM.put() method.
    Also, this sketch will pre-set the EEPROM data for the
    example sketch eeprom_get.

    Note, unlike the single byte version EEPROM.write(),
    the put method will use update semantics. As in a byte
    will only be written to the EEPROM if the data is actually
    different.
