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 ...

In Arduino Uno, the EEPROM space can store up to 1024 bytes. A single byte can store 8 bits of information, and 8 bits can store a number from 0 to 255. In the Arduino IDE versions prior to 1.6.2 you ...

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 ...
