Can someone help me with a simple alarm clock

[rob378]

Hi Everyone, Apologies if this is the wrong section or if ive missed anything simple but im new to labview at the moment.  I would like to create a simple user-programmable clock which shows a visible alarm (boolean LED) when the set time matches the current time.  I can currently get the current time to display on a time stamp and know how to change a time stamp into a control so that I can enter a time and date into the time stamp.  What I would like to do if possible is to make a system where by the boolean light will illuminate when a user inputtable time and date matches the current date and time.  Is there also any way to allow the LED to remain illuminated until a reset button is pressed?  Thanks in advance

See if this works ... (LV 2012 as you did not specify)

Hi, Thanks for that, where you have the alarm timestamp and 'get current date/time' going into the comparator with boolean output, I had set the comparator as = rather than > and I couldnt work out why it wouldnt function. Thanks

Probably because if you actually ever hit the EXACT time, you probably should've played lotto rather than spend all your luck matching a timestamp.  😉  I guess >= is technically more correct.

Hi, I am keen to explore into the alarm clock application. I am wondering if you have the lower version? I am using LV2011. Thank you very much 🙂

Hello ck76.

I saw your request and saved it for a previous version (LV 2011) as you asked.

See the attachment below.

Hope this helps!

Next time you need any conversion, visit this board (Official Version Conversion Board).

great! noted on the link.

by the way, can I ask you another question? if i am running a VI, then at the click of a button, i wish to call another VI (sub VI) - just like doing a function call within a main program, and I wish to make this sub VI running in the foreground, how can I do so? so far, I am able to call the sub VI, but the sub VI is at the background. in other words, I have to switch window in order to see the sub VI.
