so this is my code and the i will put two notes on the thread.sleep that doesn't work for me. basically i have this function that lights up a series of buttons (switches their color in a certain order) , then i have a function which receives the user input ( what buttons the user pressed and in what order). what i want to do by that sleep is to put a little break between the end of the color input(when the user finishes to press stuff), and the beginning of the light up ( when the buttons lightup/change their color). i think the problem comes with all of the these try and catch functions or however they're called (sorry i am a beginner) however i don't know hwo to overcome this.
