digital lock system for a treasury of valuables. (multisim)

To open the treasury, the user must enter a serial binary password of 6 bits. Each bit is

entered with a manual pulse at the input CLOCK. If the entered password is correct, the

output LOCK is logic 1 and the treasury is open (you may use a green light to indicate the

action). The treasury will remain open if the value at input DATA is still 1, but if the user

enters a 0 at input DATA, then the treasury will close. Don’t forget the pulse to enter the

data!

While if the entered password is wrong, then the output ALARM is logic 1 (informing the

police) and LOCK is logic 0 (the treasury is not open). You may use an orange light to

indicate the police and red light to indicate that the treasury is not open.

The user can change the password by pressing input PR, but he/she must enter the old

password, followed by the 6-bit new password (12 bits total). If the user enters the correct

old password and a 6-bit new password, the output PCh will be logic 1. The user has 2

wrong attempts to change the password, otherwise the output ALARM will become 1.

If the output ALARM is logic 1, it would never become 0 until the user presses the input

RESET followed by the correct password.
