Create a Firebase Web App to control the ESP32 or ESP8266 GPIOs from anywhere. The access to the web app is protected with authentication using email and password| Random Nerd Tutorials
In this guide, you'll learn how to control the ESP8266 GPIOs from anywhere using Firebase. We'll create nodes on the Firebase Realtime Database to save the current GPIO states. Whenever there's a change in the database nodes, the ESP8266 updates its GPIOs accordingly. You can change the GPIOs states by writing to the database yourself,| Random Nerd Tutorials
