Arduino Tutorial 10: Save Data with EEPROM!
Did you know your Arduino has the ability to save data locally and permanently such that you can access it after you power cycle the unit? It does, and this is called the EEPROM. Although your Arduino can't store as much as a SD card, the 1kB of an Uno or 4kB of a MEGA2560 gives you more flexibility in your projects without having to get add-ons.
