On the Cornish, there is a pedestrian traffic light with a push button. Under normal condition, the green light is on for the cars to go, and the pedestrian light is red. When a pedestrian wants to cross, he/she presses on the push button and the red light turns on for the cars and green for pedestrian Design this traffic light controller. No request Initial state Request Green Yellow Red The State Table: Present State Next Transition Condition Output State State 0 1 1 Apress on the request button 1 0 2 After 1 sec After 5 sec. Hint In this design, the initial state (green-state) does not change after a certain time delay. The controller stays in the green state (state-0) as long as the button is not pressed. This is known as a conditional state transition. Three LEDs will be used to show the three colors: 1- Green to allow the cars to go. 2- Red to stop the car, and allow the pedestrian to cross the street (during 5 seconds) 3- Yellow to show the transition from Green to Red status (1 second).
