problem uploading to arduino

I've been using my new Arduino (Boarduino) for about a day now and it was working fine until a couple of hours ago. I went through all of the uploading trouble steps on the Arduino website on my Mac and I still don't understand why I'm getting this error, the error is:

Binary sketch size: 1054 bytes (of a 30720 byte maximum) hardware/tools/avr/bin/avrdude -Chardware/tools/avr/etc/avrdude.conf -v -v -v -v -pm328p -cstk500v1 -P/dev/cu.Bluetooth-PDA-Sync -b57600 -D -Uflash:w:/Users/jacobrozansky/Downloads/arduino-0016/examples/Digital/Loop/appl et/Loop.hex:i

the non verbose terms would be:

avrdude: stk500_recv(): programmer is not responding avrdude: stk500_recv(): programmer is not responding


I might have accidentally changed my serial Port but I don't think I did, how do I find the name of a serial port?

If anyone has any answers to this it would be greatly appreciated :)

yep, you changed the serial port, unless your Arduino is plugged into Bluetooth.

Your error shows you are using /dev/cu.Bluetooth-PDA-Sync

This should be something like /dev/tty.usb-blah
