Once again Dave Van Wagner has published an interesting and useful project of interest to Arduino users, which describes a neat EEPROM shield. For the uninitiated, an EEPROM (Electrically-Erasable Programmable Read Only Memory) is a type of memory that retains the information when the power is removed - idea for storing more permanent settings, data logging and more. Dave's shield uses EEPROMs with the I2C interface, which allows for very easy read and write access in Arduino sketches, and also multiple EEPROMs in a single circuit.
Furthermore Dave;s shield is designed to work with 3.3 and 5V boards for maximum compatibility. For complete details, check our Dave's interesting website. And for more, we're on twitter and Google+, so follow us for news and product updates as well.
