Arduino changing serial com ports


    Jul 23 2013 | 4:14 pm
    Hi I am creating a permanent installation using an arduino. The install needs to start up and run on its own on a mac mini. I have noticed that the arduino jumps between serial port a and c every time I restart the computer. I tried to get around this by including message "port usbserial-A4001lMt, open" but I'm worried that this will change too. Is there anyway to get around this or to specify whichever port the arduino is using every time?

      Guess you don't need the answer any more, but i will write it anyway. if you keep arduino connected to the same usb computer port and use the name of the port instead of a, b, c etc you should be fine….
