When I uploaded the code arduino IDE and run on cmd I got this error message. Sometime this message not come and loading image message appear. But image not capture. Why is it happened? Hardware connection issues?
javax.comm.portinuseexception: port currently owned by unknown windows application at javax.comm.commportidentifier.open(commportidentifier.java:337) at code.simpleread.(simpleread.java:40) at code.simpleread.main(simpleread.java:29)
The error tells you that the serial port you're trying to use is already in use by another application. As you don't provide any more information about your setup (wiring, code, link to hardware, etc.) we cannot help you further.
If "cmd" means you are at a command prompt, then the GUI has attached the serial port and the runline environment cannot attach the port. Close GUI.
Now that error is ok But the image is not captured. Only Looking for images appear on cmd.
I follow this website and this video.

I attached my hardware connection.
And screenshot cmd.
Ok Thank u
I can see two probably reasons for this: Either a wiring error or you didn't upload the sketch to the Arduino.
