NodeMCU ESP32 Part 3 Simple Wifi Server with Static IP

Thank you for this excellent video. 👍I have a question about the "port number". We see that you picked "port 80" for this example. Is that number aribrary, or does it have to be port 80? From what I recall of a computer networks course, the port number allows multiple devices to share the same IP address. I think port 80 belongs to the PC we're running off of. Please forgive my ignorance? The reason I ask is that I was wondering if it can be anything to control a large number of devices with the same IP address. Thank you!

Don't be sorry. In fact, I find this question as a good one. I had the same idea at first, theoretically. However, when i change the port to something other than 80, it doesn't work unfortunately. I would advice you to experiment it and see how it works from your end :)
