Gravity: I2C EEPROM Data Storage Module

Arduino has a small amount of data storage space, The Arduino UNO has 32K and doesn't have enough space if you want to store a lot of data. We have added an EEPROM Data Storage Module to increase its storage space. The EEPROM Data Storage Module transmits data to the Arduino UNO using I2C Protocol. It uses 24LC256 256K I2C CMOS Serial EEPROM. The 24LC256 is a 32K x 8 (256Kbit) Serial Electrically Erasable Programmable Read - Only Memory. It can also be used with the Interface shield board by I2C on Board.
