When you power cycle or
When you power cycle or switch of the ESP32 all variables are lost. So how do you save your settings? In this video I show how to create a config file so you can store any number of variables. There are two versions of the code on Github, namely one using the SPIFFS library and one using the LittleFS library. If you are using the ESP32 board library v2.0.4 or newer, please use LittleFS, otherwise use SPIFFS. The video explains the SPIFFS version, but the LittleFS code works just the same.
