Hello, i am working with Arduino and python IDLE to control the servo motor. Everything seems to work in the beginning but then afterwards everything breaks. The arduino port com3 just dissapears. The arduino is connected to the computer but it is not being read. also here is the error code that i get in the python IDLE;
Traceback (most recent call last):
File "C:\Users\David\Desktop\AdruinoServoFiles\pythonServoController.py", line 29, in
ser = serial.Serial(usbport, 9600, timeout=1)
File "C:\Python26\Lib\site-packages\serial\serialwin32.py", line 30, in init
SerialBase.init(self, *args, **kwargs)
File "C:\Python26\Lib\site-packages\serial\serialutil.py", line 260, in init
File "C:\Python26\Lib\site-packages\serial\serialwin32.py", line 56, in open
raise SerialException("could not open port %s: %s" % (self.portstr, ctypes.WinError()))
SerialException: could not open port COM3: [Error 2] The system cannot find the file specified.
thank you very much.
