Change Status button and multiple SSID

Good afternoon fellow, as I do from the Arduino to change the state of a button ?. Another question is that since ESP12e connect to a network list in the order they dispose or deliver a pre-scan, any ideas?

Cheers

Sorry, didn’t get your question.

thank you very much for your answer, what I mean is that I have a NodeMCU ESP12e and at home two WiFi networks, I’m thinking about how to make connecting to the network with better signal or make it available. Excuse my English’m using translator.

Cheers
