flickering led during one time

[jajassa]

Hi,

i would like to know how could i flicker a led during a little time. This led flickers at a moment and i would like to stop it a few seconds after.

You can try to use the "Blinking" property of the LED. The blinking rate is set in LabVIEW's options in the "Front Panel" section.

i find the options in the front panel but nothing about the blinking of the led. Can you explain how do you your option, please?

[smercurio_fc]

In that section of the options:

uncheck the "Use default" checkbox and set a value that's appropriate for you. Note that this only applies to the installation of LabVIEW on the computer that's running your software. If you run your code on another computer, that installation of LabVIEW will have its own settings.

Thank you for your help but you didn't understand my issue. It's not the rate but the time of blinking of the led. I'd like to know how to stop the blinking in the program if i don't stop the blinking, the led blinks all the time.

Hello jajassa,

create a property node for your LED and select the property "Blinking". Now read the help text for this property 🙂

Hi jajassa,

you need to open 2 property nodes of the led you want to blink. Than you can use an sequence structure. put the first property node in the first frame with an true connected to the blinking property. put a time delay or code in the second frame. and put the second property node with a false constant  wired to the blinking property in the third frame. See example.

greetings,

BartB

Thank a lot everybody, and now i've an issue at the base of the blinking because i 'd like to begin the blinking at 1 point of a courbe. How could i do?

THX by advance.

[bartb]

what do you mean by at the courbe...?

[jajassa]

Excuz me i wanted to say from a point of a graph. I've got a graph and i would like that the led blink from a point so i think that i must to do it maybe with (x;y) of the point.
