Hi Ian, I'm from Argentina. I'm trying to make this, as I found it to be motivating for learning some things about Arduino, and electronics. I haven't found a store nearby that sells the DIN socket. Do you believe I can use the data bus from a USB cable to make the connection to my computer? And most important, that my computer will be able to make the sound? Thank you in advance, and I apologize if my english's bad, it's been a while since I've had to use it.
