I am building a MATLAB GUI to control a motor using the motor shield on an Arduino. I can connect to the arduino and send commands to the motor just fine. Problem is I have added a push button to 'clear' the arduino object so that it doesn't remain attached after I close the GUI. I connect to the arduino by creating an object "ardobj=arduino('com5','uno')". If I do this from the command window then "clear ardobj" breaks the connection and clears out the object. I have a pushbutton on the GUI that causes the same command to be executed, but the connection is not broken. I know this because if I close the GUI and try to connect to the arduino from the command window I get an error message. What is different about the clear executed from within the GUI?
