Do I need to buy usb cable seperately?

Yes,you need,the USB cable is not included.Many thank and best regards.Pinto Elettronica Italia

With the Arduino Uno R3 connected to a PC VIA USB will I be able to read/write to the i/o lines from the PC?

Yes provided you download Arduino IDE.

Does it have built-in wifi?

Hi there, no, the uno would require a WiFi sheild attaching to it. Hope that helps

hello, can you confirm that these are original Arduino products and that they have "made in italy" not "designed in italy" on the board? many thanks

Hi Sud,Glad to be of help. The Arduino UNO R3 I ordered back in January of this year does have "made in italy" on it. It also came with what I believe was the correct packaging and I believe it to be genuine. However, I went back to check my review and see that the UNO offered now is £11-55 against the £21-01 I paid and I see that the supplier is different. Now a bargain is one thing but I think that around £20 or so is the going rate for a genuine UNO and I suspect that for £11-55 you may get a clone. I notice that the page does not claim to offer a genuine UNO. Searching amazon for "UNO R3" I found a model claiming to be genuine for £21-89 and I think this may be what you are looking for. I would add that I have a genuine UNO R3 so that I can test stuff that I can put on my website using this as the "reference" arduino design, but I do also use cheaper clones but only after using the genuine model as a prototyping board. It may be a bit naughty of amazon to change the supplier like this and leave the reviews in place. Hope this helps, please ask any other questions you may have.Regards,EddieB.
