Design a state diagram using the following scenario :
You are designing the entrance for a Vehicle Storage system. There is a sensor that will be on high if a vehicle is in front of the gate. Once the sensor is activated, a password is required to open the gate. If the password is correct, the gate will be open. Otherwise, the gate will still be closed. And there is an exit-sensor which detects the car exiting from this gate, however, if there is a car in front of the gate at the same time, the gate will be closed immediately to process the next car.
There shall be 5 states: IDLE, waiting for the password, the password is right, the password is wrong, and CLOSE. (Correct passwords are 1 for password_1 and 2 for password_2)
P. S.
1. What are the password inputs? 2. What is the CLOSE state for?3. What is IDLE state for?
