Interface Python and Arduino With PySerial: Over the last few months I have learned how to program with Python. With one of the upcoming projects that I am working on it would be nice to have a computer’s display to view the data collected by a rover in real-time as well as crunch numbers w. My first post on here. I am trying to send - receive Python3 Arduino. I had this working with Python2.7 now would like to convert to Pyhon3. Python2.7 code that worked.

This can be done by writing ”.encode” behind the variable, e.g.
