In this tutorial I will show you how to use Arduino built in eeprom to preserve data so it is not wiped out when Arduino is restarted.We will be writing single byte values, sequence of byte values but also writing more complex data structures to that memory.This video also provides information about all memory pools at your disposal when programing your arduino.

Here is the link to the full tutorial

EXPANDED TECHNICAL DETAILS

Persistent Data Storage

This project focuses on using the Arduino's internal EEPROM to store critical data that survives even after the power is turned off.

  • Memory Cell Management: Explains the difference between RAM (volatile) and EEPROM (non-volatile). The Arduino Uno features 1KB of EEPROM, which can store configuration settings, high scores, or last-known sensor states.
  • EEPROM Lifecycle: Highlights the importance of using the EEPROM.update() function instead of write(), which only writes data if it has changed, significantly extending the life of the flash memory cells.

Use Cases

  • Self-Calibrating Sensors: Can be used to store calibration "Offset" values that the Arduino applies every time it boots up, ensuring long-term measurement consistency.
