A guide to EEPROM

Learn how to use EEPROM, short for electrically erasable programmable read-only memory, on Arduino boards.

The microcontroller on the Arduino boards have 512 bytes of EEPROM: memory whose values are kept when the board is turned off (like a tiny hard drive).

Functions in the EEPROM class is automatically included with the platform for your board, meaning you do not need to install any external libraries.

Hardware Required

All of the following boards have an EEPROM:

• Arduino UNO Rev.3
• Arduino UNO WiFi Rev.2
• Arduino Mega 2560 Rev.3
• Arduino Nano Every
• Arduino Micro
• Arduino Leonardo
• Arduino Nano
