In this book we are going to; Build a breadboard circuit using the ESP32 microcontroller board, combined with a Relay and some jumper leads.
Install & set-up the Thonny Python IDE
Install MicroPython Firmware on your ESP32 microcontroller board.
Make a MicroPython Web Server program to run on the ESP32 that will allow us to switch the Relay On/OFF when we want, using a Web Browser connected locally via Wi-Fi.
Finally, we will install & set-up ngrok Secure Tunnels.
Using ngrok Tunnelling Software, we will make our ESP32 Web Server available from anywhere that has an internet connection.
All developed under Windows 11, with the code available for download.
