I am working on a servo motor that's gonna receive an angle value from matlab. Previously we were using arduino ide but there were problems in creating an arduino serial communication. Then we began using serial communication with arduino built-in function in matlab 2016.
But problem did not go away. Even a few minutes ago, the servo was doing the job. Then when we ran the program again, this popped up, again,
" Failed to open serial port COM5 to communicate with board Mega2560. Make sure there is no other MATLAB arduino object for this board. For troubleshooting, see Arduino Hardware Troubleshooting."
This has been really frasustrating ! Please guyz, anyone have any idea what went wrong here or how to solve it ??
Thanks in advance.
a=arduino(); s=servo(a,'D9'); angle=30/180; writePosition(s,angle);
