Python BreakfastSerial error message detecting Arduino

Projects Programming

Hello all,

I'm a new user, trying to use Python with Arduino to do this:

I think I'm having a problem auto-detecting the Arduino, which is currently on COM2 (USB) - error messages below.
Can anyone please help with either the arguments to tie the Arduino to a certain COM port or generally help get this working?

Thanks,
Al

I think it is because you are using a Linux python program on a Windows computer.

This is a Windows directory
C:\Python27\lib\site-packages\BreakfastSerial\BreakfastSerial.py

This is a Linux directory
/dev/.
