Suppose, BRACU has initiated a smart elevator. For moving to a specific floor, it follows the following sequence of tasks - The passenger presses the destination floor button. The button asks the system to select the direction (upside/downside). The system changes elevator status (free to engaged) and switches the floor button light on. The system closes the elevator door and moves the elevator according to the destination floor direction (up/down). The elevator sends the system the order to control if the floor that the elevator is going to get through is the destination one. The system stops the elevator at the destination floor and opens the door at the destination floor. The system switches the internal button off Pleasae draw a Sequence diagram based on the above information.
