Yes, also possible with the USB controller, or what ever other controller you use. You only need to have a Com port. Most computers still have them, if not brought to the outside, it's on the main board. If not, then use a usb2serial adapter. Serial is available on every Arduino, the cheapest one being the Arduino Nano which supports 14 digital I/O's and costs a few bucks.
Anyone already done that? If so, please share, if not, I will make it and share it, if anyone is interested.
