TR_7:
I figured so much that the 80 in "/dev/ttyS80" in your script should be changed to the com port that arduino is using, but i couldn't come any further.
The whole of "/dev/ttyS80" has to be replaced with the Windows equivalent - probaly "COMxx", but I am no good on Windows stuff.
If you are not good at programming then what @zoomkat suggested may be a solution.
