Hello friends,
I am working on a project in my humble house - controlling the AC over the internet.
Already figured out the way I am going to do it, and I just recieved my ESP8266 Module from ebay.
The module looks like this -

And I really cant understand they way It works, there is not a single project online that has been used by this exact module!
Any help please?
Thanks!
It is a ESP8266 module which can be connected to UART (3.3V!) of some microcontroller and used for networking over WiFi with AT commands, some library or with your own sketch in ESP8266.

Unless you really want the experience of rolling your own hardware/software you should consider looking at the Sonoff devices as they should like they will do exactly what you want. If your not sure about the e-WeLink app then several people have flashed the Sonoff with alternate firmware to use other home automation systems.

That being said, how do I connect to my arduino board, and connect to a wifi? I cant get to send AT commands to it. any example around?

I really do want to learn doing it by myself
what Arduino board? is it 5 V or 3.3 V?
I did not know you can use the esp8266 as standalone, anyway I would like to connect it to the arduino. any help?
It is a normal arduino uno 5v.

sorry, it will be my last try, i promise:you can now start to learn how to bring the esp8266 togehter with the arduino, how to level shift 5/3.3, learn how to send the AT comands for establishing an internet connection, or you "just" learn how to set up the arduino ide and how to programm the esp.
I guess Using Arduino IDE | Adafruit HUZZAH ESP8266 breakout | Adafruit Learning System is pretty much all you need in the first step (or any other link google will bring up).
The learning curve is the same, but the possibilities are far better
80MHz and 500KB free to use ... if these aren't arguments.
I don't have any input and output pins, how can I use it as standalone ?
now your problem is that you have a 5 V Arduino and a 3.3 V ESP8266 module. you should ordered a version with 5 V adapter board. you need level shifter

Sorry to say that if the OP has the module linked in #6 then it has built in 3.3V power & logic level converters.
The first problem will be the modules default baud rate is 115200 so cannot work over Software serial to allow the OP to test/debug on the Arduino unless they put UNO into reset state and talk direct to ESP via serial window or program the UNO to set and save a lower baud rate suitable for software serial.

thank you. the it is perfect to connect serial to serial with Arduino board.
next is, what firmware is in it. if the standard SDK firmware, then AT commands or WiFiEsp library can be used on atmel side.
lcd or telnet can be used instead of serial monitor
