Hey everyone,
Thanks alot for the demo files, I will try them as soon as I receive my radino WiFi.
did you hear about radino? They already merged the ESP8266 and an Arduino Micro into one single module. (www.radino.cc) and the whole thing runs on 3.3V.
They also provide a Arduino-support package on their website, e.g. containing a simple webserver example for the ESP8266. Maybe this will help someone with their first steps on ESP8266.
