I got a project which is the Alarm clock. It is build on case structure. My project should start beeping when it's a alarm. I already got beep sound when it's comes to set alarm but I can't manage to end beep sound when I click to turn off the alarm. How can I do this?
Well, show us your VI and we show you how to fix it. Obviously,you made a mistake, but your description is way too vague to give constructive advice.
An alarm system involves much more than a case structure, in fact it could be done without one. (Your post is like saying: I think my formula is wrong. I won't show you what I did, but I used a pencil)
What is your code architecture?
What timing functions do you use to measure the time?
A project does not beep. A sound output device does.
How is the time set? (absolute time? Relative elapsed time?)
How do you detect an alarm condition?
How do you try to turn it off (mechanical action, etc.)
