Tutorial how-to : ESP8266 web server (WiFi AP) to remote control a servo

[@YUHYEJUN]

Wow..
ESP8266 is amazing.
It is cheap and has many functions.
I didnt know esp has AP mode.
I am trying project using exp8266.
I will watch your code and improve this.
Thank you for sharing good implement.

Nice piece of code, can you make it available as text file? thnx

thanks Hugues,
i will use the code as a base for a "flexible" IOT sensoring system (kWh, Water, weather, etc...) for my domoticz server.
The flexible means you can configurate all the static parameter with the web-interface.
your code gives me the basic that i need. it's all about web interactions with the IO.
later on i shall publish it on RUclips

Nice, yes post your results!
