Cannot connect Arduino Uno

[Jenny Rodenhouse]

I have Arduino Uno

/dev/cu.usbmodemfd131 tried both ports

opened NetLabHub in 32 bit

Can't seem to get passed the first stage of getting started, simply connecting my Arduino. I've typed in the port info as: 

In flash CS6 I get this error, something seems to be wrong with the serial library??:

Any suggestions on how to fix would be great. Thank you!

I looks like you are using an older version of the Hub and widgets. Try the 5.0.1 version. When you first try to connect, you should see a message from the Hub asking you to fix the serial issue. By the way, in the current version of the Hub, you don't need to change it to 32bit either.

The solution to the problem is listed on NETLab ToolKit Download page, below is the link.

• However, there may be an issue where you get an error message when you first try to connect to an Arduino.
  If you see the error message “Please use Tools ? Fix the Serial Library.“, do the following in the terminal app:
  • sudo mkdir /var/lock
  • sudo chmod 777 /var/lock
