Create an elevator using digital logic/ D flip flops see below for details.

The system has 2 inputs and 3 outputs

Inputs

1 or Down - It represents a button located inside the elevator or on the first floor, which may be used to take the elevator to the first floor, from any floor.

2 or Up - It represents a button located inside the elevator or on the second floor, which may be used to take the elevator to the second floor, from any floor.

Outputs

1st floor- When this output is equal to logic I, it indicates the elevator is at the I. floor.
2nd floor- When this output is equal to logic I, it indicates the elevator is at the 2. floor.
Door- When this output is equal to logic I, it indicates the elevator door is open.

Details about the design:

The system has four states, 1st floor open door, 1st floor dosed door, 2nd hour open door, and 2nd floor dosed door.

The elevator should remain at rest until someone presses a button. The rest states are defined to be the states where the door is closed.

If someone press the 1 or Down button, the elevator should go to the 1st floor, open the door (1st floor =1, door =1) and remain in this state for a small amount of time, then close the door (1n floor =1, door = 0).

If someone press the 2 or Up button, the elevator should go to the 2nd floor, open the door (2.a floor = 1, door = 1) and remain in this state for a small amount of time, then close the door (2.d floor = 1, door = 0).

• Implement the circuit using flip-flops of your choice.
• Use Multisim to simulate your circuit and implement it on the breadboard.
• Document your design, simulation and experimental results in your project report.
• Prepare a few slides for a 5-minute oral presentation.
