About This project demonstrates how to use an Arduino UNO to read and write data to an AT24C256 EEPROM over the I²C (Inter-Integrated Circuit) bus. EEPROMs like the 24C256 are used for storing data ...
This is a useful addition to my previous article “Arduino EEPROM”. The article is still available. I have provided a link here for convenience https://www.edn.com ...
The AT24C256 EEPROM provides a small amount of permanent storage for the Arduino, but can be tricky to use. The Hobbytronics website has an excellent article explaining how to use this EEPROM.
