Build a breadboard circuit using the Raspberry Pi PicoW low-cost, high-performance microcontroller board, combined with a Relay and some jumper leads.
Install & set-up the Thonny Python IDE
Install MicroPython Firmware on your Raspberry Pi PicoW
Make a MicroPython Web Server program to run on the Raspberry Pi PicoW that will allow us to switch the Relay On/OFF when we want, using a Web Browser connected locally via WiFi.
Finally, we will install & set-up ngrok Secure Tunnels.
Using ngrok Tunnelling Software, we will make our Raspberry Pi PicoW Web Server available from anywhere that has an internet connection.
All developed under Windows 11 with the code available for download.
Sounds like it might be fun, let's go.
