Arduino has a small amount of data storage space, The Arduino UNO has 32k. It doesn't have enough space if you want to store a lot of data. Therefore, we need to add an EEPROM Data Storage Module to increase its storage space. The EEPROM Data Storage Module transmit data to Arduino UNO using I2C Protocol. It used 24LC256 256K I2C CMOS Serial EEPROM provided by Microchip Techonogy Inc. 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..

Jargon buster
Plain-language definitions for the technical terms used above.
- EEPROM
- A type of non-volatile memory that keeps stored data even when power is turned off. In a sensor module, it can be used to store settings or calibration data so they do not need to be re-entered every time.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- Shield
- An add-on board that plugs into a main controller board to give it extra features such as sensing, motor control or communication. Knowing a product supports shields helps you judge whether it can connect neatly into an existing maker-board setup.
