Raspberry Pi Pico W
Making A Basic Web Server
This page sets up a basic web page served from the Pico W.

You use the IP address that is printed to connect to the Pico W from another device on the same WiFi network. Make sure that you are on the same network. In a home, that's unlikely to be a problem. In a school, your WiFi and wired networks may not be the quite the same. I used a phone to connect to this page. The basic HTML is rendered quite small on a phone so I zoomed in for this test shot. You can use frameworks for responsive design to do a more phone-friendly job in more advanced projects. This is just to get things working.
