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 ...

SparkFun Qwiic EEPROM (COM-18355) A simple-to-use I2C library for talking to any EEPROM. It uses the same template system found in the Arduino EEPROM library so you can use the same get () and put () ...

The EEPROM chip that I'm using is the AT28C25615U from ATMEL. I decided to use an Arduino shield with a ROM socket to flash a ROM file from my computer to the EEPROM.

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 ...

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 ...
