So I'm sure this is a question which is answered many times elsewhere, but the internet is so flooded with various sources, I'm having a really tough time wrapping my head around this. For instance, right now, I have working this sketch: https://gist.github.com/igrr/9ef4d5c74355503e3b1f . All is well, it's working fine, but I can only access it by typing the network ip if I'm on the same LAN. How do I go from this to, say, being able to move this servo while I'm at the library or wherever?
Thanks for the help
