5 LEDs are circulating one by one at 1 sec interval.( LabView VI)

Hi everyone, I am new user for LabView. May I know how to make 5 LEDs are circulating one by one at 1 sec interval.( In LabView VI). Thanks.

I only have a Rube-Goldberg-Machine for this problem. It may work for you or not ...

Joke apart:

It looks like an educational exercise and you should solve it by yourself. If you get stuck, then post your VI and we can help you with the next step.

There is actually an example of this in the actor framework project template! Take a look at the "launcher.vi" after loading the template

Your problem is much simpler than the problem solved here  (fewer LEDs, no random skipping, etc.). I am sure you can simplify it accordingly. Done correctly, the code will be trivial and fit on a postage stamp.

Fantastic code and really funny in the details!. Definitely belongs into the Rube Goldberg thread. 😄

When you say "circulating", do you mean that the LEDs are arranged in a circle? (Thus my reply above).

If they are arranged linear, use an array of LEDs (have a look here). Of course there are many equally simple alternatives to solve this.

As an exercise, see if you can recreate the following code:

may i ask the what is the name of this tool? Thanks

Hi David,

its a function to manipulate arrays, so it can be found in the array functions palette!

Hint: it does not insert, but replace…

another option would be to start with a boolean array constant (where one is true) and simply "rotate" the 1D array each iteration of your while loop.

I Heard good things about the Rotate function and number to boolean Array.
