 - The EEPROM requires careful management of write operations since flash memory has a limited number of write cycles (100,000). Avoid writing to the same address repeatedly in tight loops, as this will quickly wear out the memory. Instead, only write when values actually change, and consider spreading data across different addresses to distribute wear evenly.
 - Keep in mind that EEPROM stores data as individual bytes (0 to 255), so larger data types need to be broken down or use the `put()` and `get()` functions for automatic handling.
-- The EEPROM retains data for over 10 years under normal conditions, making it excellent for long-term storage of configuration data and user preferences.
