## Questions & Answers

**Q: Do I need to buy usb cable seperately?**
A: Yes,you need,the USB cable is not included.Many thank and best regards.Pinto Elettronica Italia

**Q: 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?**
A: Yes provided you download Arduino IDE.

**Q: Does it have built-in wifi?**
A: Hi there, no, the uno would require a WiFi sheild attaching to it.

Hope that helps

**Q: 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**
A: 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.
