2    eeprom_put example.
3
4    This shows how to use the EEPROM.put() method.
5    Also, this sketch will pre-set the EEPROM data for the
6    example sketch eeprom_get.
7
8    Note, unlike the single byte version EEPROM.write(),
9    the put method will use update semantics. As in a byte
10    will only be written to the EEPROM if the data is actually
11    different.
