EEPROM costs nothing to use if it’s included with your Arduino (see FRAM below if your board doesn’t have EEPROM).
Think of EEPROM as a tiny flash drive built in to your Arduino. This means that data saved to the EEPROM can be read using a sketch even after the Arduino has been turned off and turned back on. EEPROMĮEPROM is a section of memory that is safe when the Arduino loses power. If your project involves working with data in any way, check out my complete guide here: /analyze-data-using-arduino/ 1. I wrote this guide as part of a series on Arduino data analysis. To analyse data on another device, try storing the data in the cloud.To collect data over a long time that will be shared with a computer, try an SD card.
The best ways to store data depend on your project: Ways Arduino can store data collected from sensors
