This is not an easy task, but it explains the basics for setting up a wireless network through Arduino. Basically there are a two sites that when combined gives the right information: http://www.instructables.com/id/Using-the-ESP8266-module/?ALLSTEPS http://shin-ajaran.blogspot.se/2014/12/noobs-guide-to-esp8266-with-arduino.html The 3.3v seems to work fine and the module looks happy. The output isn’t spot perfect so there might be some …
