incrementResourceCount (arduinoObj, 'servo')
decrementResourceCount (arduinoObj, 'servo');		% In destructor

Input Arguments

Arduino object, specified as an object that is an internal variable called from within classes that derive from matlabshared.addon.LibraryBase.

Name of resource to decrement, specified as a character vector. The resource must be added to the arduino object before using incrementResourceCount.
