I once built a METAR light map like this - https://slingtsi.rueker.com/making-a-led-powered-metar-map-f...

However, I did it with an ESP8266 running MicroPython; I was impressed that such a small, cheap little computer was able to connect to the internet, retrieve XML, parse it (this step in particular), and update the state of each of the WS8211 lights with ease, all with some quick, easy-to-write Python.

I have an ESP8266 wired into my intercom buzzer for opening the door remotely[0]. It has been unreasonably stable and reliable. Many months, possibly into years, of consecutive uptime. I used the arduino IDE and modified demo code for a web server. The cheapo dev board had it's blue LED die (mercifully) but is still chugging along. It's crazy what these things can do.
