Hi,
Thanks for the responds. Yes I have selected the right board.
I contacted my friend and the told me that he just gave me an usb-cable that had the correct connectors on it.
So now we are going to check if the arduino works on his desktop while using the same usb-cable as I am using now.
I will post if this was the problem. Because frankly I think if that is not the problem, the arduino itself must be defect.
Regards,
Stieve
