Connecting 2 cases

[mrspaceman]

Im sorry but based on your code , i still can lock and unlock the door without the correct password . That's not right

Try something like this (lock and unlock buttons need to be pressed until the door has reached the end state).

Since the number buttons are latch action, one of them is always true and the inner case is not really needed.

really appreciated your help but the point is the door need to be automated with 1 press

Guys, I do not wanna be too rigorous, but you are close to give a final solution of a home work I think. The OP should really start learning more LV basics, and not waiting for a final solution 🙂

There is still a lot of Rube Goldberg code in there.

• The number buttons should be latch action, so one is guaranteed to be true if the event fires, simplifying the code.
• There is still no reason for the timeout case.
• That case structure with 9 cases and 9 diagram constants is very hard to maintain. See my code for an alternative
• The fedback node is still wired incorrectly. Don't use the previous value to calculate the other displays, but the current value.
• Should one be able to lock without password or do both lock and unlock need it?

Thanks for the comments. and i went through your code  and looks good take your comments

Provided solution from his own code to to build his confidence that his code works to some extent.

If i try to build a code hope it will answer all your questions

Some general comments:

Try to use a radiobutton for the operation to avoid the case where both buttons are true.

Instead of using case structures, you can just disable controls if they should not be operated. Better feedback to the user.

Here's a quick modification

It's perfect the solution from you . Thank you so much .
