EEPROM data. The arduino has three memories, being data memory, EEPROM memory and code memory. The division of these memories in different locations is called a harvard architecture. This is different from the von neumann architecture used on the PC. The view of the EEPROM data allows you to see what is inside the EEPROM. This is a simple dump.
A lot of modern microcontrollers – such as the ATmega328 – contain some built-in EEPROM, but that doesn't mean that you can't add more! Serial EEPROM devices like the Microchip 24-series EEPROM allow you to add more memory to any device that can speak I²C. Today we're going to learn how to read and write serial EEPROM devices using Arduino.
The Arduino Uno is a microcontroller board based on the ATmega328. It has 20 digital input/output pins (of which 6 can be used as PWM outputs and 6 can be used as analog inputs), a 16 MHz resonator, a USB connection, a power jack, an in-circuit system programming (ICSP) header, and a reset button.
When used in Arduino, you can read/write files to it, like a little datalogger or SD card, and then with our helper program, access the files over USB. Easy reprogramming , comes pre-loaded with the UF2 bootloader , which looks like a USB storage key.
An inspiring example of this is the Maccabeam, an automated light up Menorah designed by Samuel Goldstein that offers a modern take on the seven-branched candelabra that is traditionally illuminated over the course of Hanukkah.
EEPROM (also E 2 PROM) stands for electrically erasable programmable read-only memory and is a type of non-volatile memory used in computers, integrated in microcontrollers for smart cards and remote keyless systems, and other electronic devices to store relatively small amounts of data but allowing individual bytes to be erased and reprogrammed.

Operating Voltage: 5V or 3.3V(choice by slide switch) Digital I/O Pins:14

Aug 22, 2018 · EEPROM EEPROM is another form of non-volatile memory that can be read or written from your executing program. It can only be read byte-by-byte, so it can be a little awkward to use. It is also slower than SRAM and has a finite lifetime of about 100,000 write cycles (you can read it as many times as you want).

Arduino is an open sourced electronics platform that is based on easy to use hardware and software. An Arduino board receives inputs and outputs that enable it to perform various tasks like control motors, LEDs, remotes and much much more.
