EEPROM stands for Electronically Erasable Programmable Read-Only Memory. It allows values to be written and stored for lengthy periods of time with extremely minimal power consumption.

The I2C protocol is a two-wire interface, which means there are two signal lines on the bus: clock and data. Both signals are connected to every device on the bus. A master transmits a start bit followed by a control byte when it wants to connect with one of the devices on the bus.
