Hi , I am doing an ANTI BREAK-IN in Labview. My concept: 1.Password 5791a 2.after the password is accepted, only 5 secs, the alarm is armed, so that the user can leave the house. 3.When the user comes thorught the front door( Zone 1), he/she has 5 secs to enter the password, else alarm will go off. 4. Every time the alarm goes off (the pareticular zone LED blinks), siren also sounds. My problems: 1. When the switch is turned off, the alarm also goes off. I want the alarm to be on once it is on.( did what you suggested in my previous post, but did not seem to work) 2. When the RESET button is pressed after typing in the passowrd to disarm, I want the program to run, but all switches and LEDS back to its original state. NOTE:You can delete the sound VI, if its doesnt work.

I did it.Phew!

my new problem:

in the last stage: to disarm the alarm once the alarm is on, my logic is to check the password again.

But i want to give the usera chance to attempt password 3 times , how can i do that?
