The ieee campus society office sells sodas for 35 cents. suppose they install a soda controller that only takes the following three inputs: nickel, dime, and quarter. after you put in each poin, you push a pushbutton to register the coin. if at least 35 cents has been put in the controller, it will output a soda and proper change (if applicable). draw a finite state machine that describes the behavior of the soda controller. each state will represent how much money has been put in (hint'. there will be seven of these states). once enough money has been put in, the controller will go to a final state where the person will receive a soda and proper change (hint: there are five such final states). from the final state, the next coin that is put in will start the process again.
