I am not sure how to solve this problem. Any help would be greatly appreciated. I am a little new to processing but I could not find this problem in the forums.

Find your Arduino in the list below, note its [index]:

Stable Library

=========================================

Native lib Version = RXTX-2.1-7

Java lib Version = RXTX-2.1-7

[0] "/dev/tty.Bluetooth-PDA-Sync"

[1] "/dev/cu.Bluetooth-PDA-Sync"

[2] "/dev/tty.Bluetooth-Modem"

[3] "/dev/cu.Bluetooth-Modem"

[4] "/dev/tty.usbmodem621"

[5] "/dev/cu.usbmodem621"

To use the serial library, first open

Applications -> Utilities -> Terminal.app

and enter the following:

sudo mkdir -p /var/lock

sudo chmod 777 /var/lock

Exception in thread "Animation Thread" java.lang.RuntimeException: Please use Tools ? Fix the Serial Library.

Here is the code I used.
