and everything is working fine on my arduino board.
In processing, I changed the portname to
String portname = "/dev/tty.usbserial-A4001mmw";
which is what i am using in arduino...
but there is this error : gnu.io.PortInUseException: Unknown Application
at gnu.io.CommPortIdentifier.open(CommPortIdentifier.java:
354) What is it? please help! ::

Thanks. Alisha
You might also need to run the macosx_setup.command. See the Processing serial library page for more troubleshooting suggestions: Serial / Libraries / Processing.org
Thanks a lot for your help!... Well, it's still not working at all... no idea why. The serial monitor in arduino was closed.. Well, I will look at the Processing's link right now. Best-Alisha
