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
