    Iterate through each byte of the EEPROM storage.

    Larger AVR processors have larger EEPROM sizes, E.g:
    - Arduino Duemilanove: 512 B EEPROM storage.
    - Arduino Uno:         1 kB EEPROM storage.
    - Arduino Mega:        4 kB EEPROM storage.

    Rather than hard-coding the length, you should use the pre-provided length function.
    This will make your code portable to all AVR processors.
