As another example of using EEPROM to help the user, say that you turn your Arduino into the heart and mind of a servo-based actuator, for example an electronic door lock or an automatic pet feeder.

An EEPROM can store data permanently unless you erase or overwrite it and won’t lose the data when powered off. Some microcontrollers like Arduino have very limited internal storage space, so an ...

Since the ST24C04 512-byte device in question has an I 2 C bus it’s a straightforward add-on for an Arduino Mega, so we’re shown the wiring for which only a couple of pull-down resistors are ...

We’ve seen projects test the lifespan of an EEPROM before, but these projects have only tested discrete EEPROM chips. [John] at tronixstuff had a different idea and set out to test the intern… ...

Meet the Arduino Compatible RFID Reader Module. It can hold card data for up to five cards, takes seconds to program, and holds card data in EEPROM memory, which means that the cards are saved ...
