Switching a boolean between two states

[Kim]

Hello

I'm new to Labview and i have a question regarding how to make a
boolean control to switch between true and false automatically.
For example, when i run the vi i want the control to be true for
1 sec. then false for 1 sec. and so on. ?

thanks

Noor

Noor,

I'm new to LabVIEW too, but here is the way I would think to do it (though,
it may not be the best)

Create a while loop.
Inside the while loop, create a sequence.
Let the first frame be to wire a true constant (in functions -> boolean) to
your control
let the second frame be a wait timer set to 100ms
let the third frame be to wire a false constant to your control
let the fourth frame be another wait timer set to 100ms

I doubt this is the best way, but it is what came to mind.

That's close, except the sequence is unnecessary. All you have to do is carry the boolean value in a shift registers and invert it with every iteration.
