Hi I want to communicate threw the serial port with an python code on a windows pc. The Arduino is connected via USB with the PC. It is the same cable which I use to upload the code to the arduino.
The upload works. Now as I run the Python Code I want to see the answer on the serial monitor.
When I want to open the monitor I get the error message that the com port is busy.
Is it possible to use the same usb connection.. or is the error related to this?
Thx for your reply/ help
