how to detect a keyboard key in a while loop using a figure

I am using arduino nano and checking push buttons in a while loop. I want to detect a keyboard key, say 'spacebar' and simulate a push button. A figure with a push button is the desired output. Everytime the figure is in focus and the 'spacebar' is pressed on the keyboard, it should turn on and off a digital output of arduino board.

myFig = figure('KeyPressFcn', @myKeyPressFcn,...
'UserData', false);
a = 0;
while true
a = a + rand;
if myFig.UserData
close(myFig)
break
end
drawnow % <- important so that myKeyPressFcn() gets called when a key is pressed
end
disp(a)
function myKeyPressFcn(src, evt)
if strcmp(evt.Key, 'space')
src.UserData = true;
end
end

I am trying to implement something similar for a spacebar clicker replica. I want to add a time interval to your code so that spacebar press is emulated after a set interval. can you please help me out here? thanks in advance.
