As the title indicates, I need to create a bridge betweeen pd and arduino UNO but I can't get it to work. I need to start an arduino process after receiving a message from my computer through puredata, using the comport object. Since comport object in pd doesn't allow me to connect to the port used by arduino (listed trough "devices" message in pd) I don't understand how to stablish a communication between them.
[comport]: could not open device COM3:
failure(5) ERROR_ACCESS_DENIED
Arduino is connected to the computer by usb cable.
