The overall objective is to design a vending machine controller. The system has five digital inputs and three digital outputs. You can simulate the system with five switches and three LEDs. The inputs are quarter, dime, nickel, soda, and diet. The quarter input will go high, then go low when a 25¢ coin is added to the machine. The dime and nickel inputs work in a similar manner for the 10¢ and 5¢ coins. The sodas cost 35¢ each. The user presses the soda button to select a regular soda and the diet button to select a diet soda. The GiveSoda output will release a regular soda if pulsed high, then low. Similarly, the Give Diet output will release a diet soda if pulsed high, then low. The Change output will release a 5¢ coin if pulsed high, then low. Implement the controller using a finite state machine. Choose a Moore or Mealy format as appropriate. Because there are so many inputs and at most one is active at a time, you may wish to implement an FSM with a different format from the examples in the book.
