UPDATE: The issue turned out to be with my work laptop. Our IT department has them configured in such a way that the assignment of serial ports is different somehow. When I plugged in on my personal Macbook Pro it all worked perfectly.
I just got my first Arduino. Its an UNO R3. I'm running OS X 10.8.5 (Mountain Lion) and the Arduino IDE 1.0.5
Under Tools>Board I have Arduino Uno selected
Under Tools>Serial Port my options are:
I've tried all of them, but when I try to upload a sketch it fails. Most give the following error:
avrdude: stk500_recv(): programmer is not responding
The two "modem" options return this message:
Serial port '/dev/tty.Bluetooth-Modem' already in use. Try quitting any programs that may be using it.
I'm at a loss. None of these serial ports seems correct but there aren't any other options.
Also under Tools>Programmer which option should I be using?
