## @deftypefn {} {@var{pinnums} =} getTerminalsFromPins (@var{ar}, @var{pins})
## Get the terminal number for each pin.
##
## @subsubheading Inputs
## @var{ar} - connected arduino object
##
## @var{pins} - single pin name or cell or vector array of pin names.
##
## @subsubheading Outputs
## @var{pinnums} - pin number of each named pin. If the input was a single string, returns a number.
## if the input pins was a vector or cell array, return a cell array of pin numbers corresponding
## to each input pin name.
