Question 2 Read following system carefully and identify actions, events and states. Finally draw a State Transition diagram using six step design approach: "The microwave oven has input buttons for selecting Cooking Time, Start, Minute Plus, Time of Day, and Cancel, as well as a numeric keypad. It also has a display to show the cooking time left and time of day. In addition, the oven has a microwave heating element for cooking the food, a door sensor to sense when the door is open, and a weight sensor to detect if there is an item in the oven. Cooking is only permitted when the door is closed and when there is something in the oven. The oven has several actuators. Besides the heating element, there are light, beeper, and turntable actuators. The microwave oven displays the cooking time, the time-of-day clock, as well as messages to the user such as prompts and warning messages To allow for international sales, the microwave oven system needs to be configurable. In particular, the display language and the type of time-of-day clock, twelve- or twenty-four-hour clock, must be selected at system configuration (generation) time." TIE
