Hello, I'm trying to configure a simple double button remote control 433 MHz with GIGA R1 WIFI using a rc receiver module DollaTek 433Mhz.
Is there a code I can use to "read" the button I press on the remote control?
Thank you very much,
ale
Which "simple double button remote control 433 MHz"?
If you mean to connect a general purpose cheap 433 MHz receiver to your Arduino, there would remain the problem of what, exactly, the remote sensd when you press one button or the other.
We can start by taking a peek at what you have in front of you. Post any technical data you have; at least provide a link to where you bought it.
Wi-Fi won't enter into this part of whatever you are trying to accomplish in any larger project. For now, that's good: divide and conquer.

this is the receiver I used
this is the transmitter I'm using
The ad claims that is an encrypted "rolling code" transmitter, typically used for garage doors, gates, etc.. No Arduino libraries can decode that signal, or transmit it, because it is specific to the manufacturer.
Super reg. type receivers with a red laquered coil are the worst you can buy.
Google for Super heterodyne.
+1 about the rolling code.

As noted you are SOL on receiving from that remote. If you have both parts, TX and RX, of the cheap 433 MHz, you could make a remote using the transmitter and one Arduino, and make a receiver with another Arduino.
There are better radio sets of the 433 ilk, again as noted. But if you range requirement isn't too ambitious, cheap ones can work well. The Radiohead library makes it very easier.
But possibly most attractive and expeditious would be to purchase a fob and receiver combination and change the nature of your probelm to hijacking the receiver, if it isn't one that directly controls relays, or simlpler to get one that does, then those relays can act like pushbuttons would in your Arduino project.

If that looks like your way to go we can help you to not waste money on something that looks good.

Further to @alto777 quality response, these are the units I'm using with my giga.
The receiver has a tiny relay which is ideal if it's just a signal you are looking to drive. It comes with a single button fob but if you need two buttons then I can recommend these fobs:
I have two of the receivers from the first link each paired with one of the buttons from the fob in the second link.
Thank you alto777 and steve9, may i ask you to give me a sample of the code I could use?
Moreover I serached but radiohead library seems not to work with remote control like the one I showed to you.
Thank you so much,

The library operates at a very low level and facilities sending data over RF.
What the data means and who creates it and who uses it is a higher level concept.
This is the way many sketches will work. Layers each building on the lower levels.
So no, the RadioHead library is probably worthless for using the remote you have. In the hands of an experienced hacker or real engineer, a time-consuming, challenging and in its own way fun project would be to get it functioning as part of some radio control device. Which experienced person wouldn't be involving RadioHead, not at first and possibly not at all.
So from the time-is-money perspective, if getting the remote isn't the entire goal, and a reasonable person might ask if so, why? you should just flip burgers or whatever it takes to afford the radio part off the shelf, like you got the Arduino board.
If you do want to use a TX/RX 433 radio set, get the best you can, then read the example code that is available for RadioHead, which will probably begin with the RF equivalent of "Hello Workd!", that first set of sketches that proves the hardware works and you can send data from one place to another.

Thank you very much, at the end I succedeed with the library RC-Switch.
