Tutorial: How to save settings to MCU's EEPROM memory
Tutorial: Learn how to use the EEPROM to save settings such as calibration values, passwords, etc. to non-volatile memory that will restore on power up, even if you have no battery backup. Shown are my favorite methods EEPROM.put and EEPROM.get that allow you to store bytes, int's floats, chars and more. Whether you use an Arduino, Teensy, or ESP32. chance are you will need to store some settings for future use. Hopefully this lesson will help you learn how to retain data.
