The … WebESP32 EEPROM Example (Arduino IDE) In this example, we’ll test the EEPROM memory by saving the last LED state. The LED is toggled by a push button, and whenever its state changes, the last state will be saved to the EEPROM. We’ll reset the ESP32 board and it should retrieve the last saved state from the EEPROM.
