I have a project working for opening and closing the windows in my greenhouse, it is controlling windows based on Temperature, Rain and Humidity, i was struggling with noise but that seems to be fixed, so now i would like to go to the next step which is to get it online, my idea is to get it connected to wifi so i can log data on RPI and send commands to arduino. my idea is to log the data to a SQL database and somehow get it published on a homepage on the RPI.
my question is how do i get the Mega 2560 on WIFI without too much hazzle (don't want to spend 6 months on google to find out how to hack some doubtfull module) ;) . looking online there is many ways to go, mostly i find the ESP8266 but many versions of that one. :confused:
I found that i need to reduce TX from Arduino to 3.3V not to cause damage to ESP8266, a tutorial shoved that it could be done with 2 resistors 10K inline and 20K to ground.

hope somebody here can guide me in the right direction :) . a little link or guide showing how to set it up so it acts togeter with the Mega 2560 would be verry helpfull i find a lot of examples on how to use ESP8266 as a stand alone unit.
