Someone have an idea how i can use this Code for Windows USB port COM1 “a = Arduino(this, ‘/dev/ttyACM1’, 57600)” this Code is for LINUX but i need it for Windows to USE Python on Arduino.  
Or somone have another Idea to use Python on Arduino?

```auto
add_library('serial')
add_library('arduino')

def setup():

Hi,  
maybe the problem is resolved now, but just in case.  
You just have to replace this line

```auto
    a = Arduino(this, '/dev/ttyACM1', 57600)

```

by

```auto
    a = Arduino(this, 'COM1', 57600)

```

and it should work.
