Hi i'm going to buy an arduino for the school final exam.
I have to control the arduino via http, through a web site wherever i'll be.
I must connect to my house lan (static ip) where my arduino will be posed.
I have a doubt toconnect with wifi (no ethernet i want only wifi) wich boards i should buy?
I have also a problem about the space, i need more! Could i put my sketches in the sd on the wifi shield and run it on the main board of the arduino (i think UNO) i'll buy?
(I am looking for the arduino uno rev3 + wifi shield, could it be ok?)
Maybe i'll need more pins to control a lot of things, i have only to buy an expansion board and connect it to the main arduino board, isn't it?
A UNO and WiFi shield would seem a good starting point for what you're describing. It is probably premature to worry about running out of space and pins before you have written a single sketch. However, if you already know you'll need more pins, program space and/or memory than a UNO provides perhaps you should be considering a Mega instead.

Does the Arduino have to be directly connected? If not, you can use your home PC between Arduino and internet with a USB cable and PC program written in Processing. Processing language is free and the code looks very much like Arduino code because Arduino language was made based on Processing. They go together well.
For a one day thing, yes you will be able to control Arduino through the web and the only code on the Arduino will simply interact with Processing on the PC.
Space on Arduino? If UNO is not enough then there is MEGA. How much code and data tables do you need? If you can do the above, it will need less of both.

Thx for the answer, i think i'll buy the "arduino mega 2560 rev3" with the "ethernet shield"!
Thx for your help, i hope i'll realize my project in time!
See you!

By the way, your English is very good!
Thks goforsmoke, in fact i'll buy the mega!
The mega is the best dolution for the menory and the pins and the wifi shield has the sd slot, much helpful to save http logs.
Hope to hear you soon, by!
