2. Construct "Elevator Simulator" using 1-digit 7-segment display 8 buttons and a Servo-motor. Display should indicate the floor at which the elevator is currently located. 4 buttons will be used to simulate floor buttons inside the elevator. By pressing these buttons numbers on display should start increasing or decreasing depending on the current and destination floors. Other 4 buttons will be used to simulate elevator-call buttons located at each floor. By pressing call buttons the elevator should come to the floor where that call button is pressed. Servo motor will simulate opening and closing door of elevator (0 degrees for closed door, 90 for opened). So when call button is pressed elevator will arrive to the floor the door will open for 3 seconds and then closed, after that the elevator will go to the destination floor pressed by the button inside the elevator, and the door will open again for 3 seconds and close. If two or more floor buttons or call buttons are pressed then the elevator should stop at each requested floor if it goes through it, but if it does not then it should return to unserved floor at the end.
