The microcontroller found on the Arduino and AVR Genuino based-board comes with Eeprom. With that space, how can we store a sentence? Arduino Uno has 1024 bytes of addressable positions while Arduino Mega has 4096 bytes of addressable positions. So adding 24LC256 chip for EEPROM expansion is a significant one. 19 Comments . May 25, 2019. On Arduino Uno you have only 1024 bytes in the EEPROM, which means 512 int numbers, or 256 long numbers. It is a form of non-volatile memory that can remember things with the power being turned off, or after resetting the Arduino. The Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328 (Arduino Nano 3.0). The work around that is to implement some data logging to an SD card or through the EEPROM. The 24LC256 EEPROM chip can be obtained for a little over $1 on ebay. There are three pools of memory in the microcontroller used on avr-based Arduino boards : Flash memory (program space), is where the Arduino sketch is stored. The desired temperature setting is entered using a keypad and stored in non volatile memory of Arduino in the EEPROM to keep the settings even during system reset or power OFF. These are memories with values which are kept when you turn off the board, such as a small hard drive. So to see how writing and reading on the Arduino EEPROM works, let’s implement a … This particular project explains how to access the built-in EEPROM of an Arduino board with the help of a simple code which writes some data into the EEPROM and reads back the same data. Each EEPROM address can save 1 byte of data. Or a paragraph? The beauty of this kind of memory is that we can store data generated within a sketch on a more permanent basis. Similarly, SDA pin ( Arduino ) with SDA pin of EEPROM IC. Write and Read values on the EEPROM. When saving a number from 0-255, EEPROM.write is sufficient. On the Arduino side I use an 1024 byte buffer to store the data bytes before they are written to the eeprom. The ESP8266 has a reserved memory area to simulate the internal Arduino EEPROM.
