That's not a useful description of the problem.
Why do you want to do that?
I've already provided a lot of information in previous threads on this forum. This one should give you the info you need:
You can find more threads via this google search (I try to use the "elecshop" keyword when I refer to the shield).

Thanks for the repy! Well, I can't even send code to the board, and I think that's why I can't get it to work. I thought that updating the firmware could help, so I tried, but without luck. I had found that thread, but even with the Blynk library it's not uploading the code to the board.
I only need to connect the shield to the arduino, connect the arduino to the PC, open the Blynk > Boards_WiFi > ESP8266_Shield. I tried to compile that and it poped up an error:
error: 'Serial1' was not declared in this scope
So I changed Serial1 to Serial and it compiled good, but I can't send it to the board! It gives some errors:
avrdude: stk500_recv(): programmer is not responding
So I googled it and there were peope saying to disconnect the RX pin, so I remembered a tutorial that said to invert the connections with pin 0 and pin 1, like this:
And it worked! I could upload the code to the board and when I open the serial it shows:
 Connecting to MARTINO WIFI
 ESP is not responding
My objective is to create a very simple webserver, I don't know if this Blynk app is what i need. And btw, my switches are:
1 - ON
2 - ON
3 - OFF
4 - OFF
What do I do now? And thank you so much!
