Controlling LED with Switch

[Eisa_Alyaqoub]

Hello Engineers, 

I am new to Labview, so please be patient with me 🙂 

In this project, I am using one switch to turn LED On/Off. 

I want to keep the LED On with one press and stays On when I release the switch, but when I press the switch the second time, I want the LED to turn off and stays off. 

I did the design, but the only way that I could do it with is using for loop with specific length (the length of the for loop such as 10 iterations) when the case structure is true. 

I attached the file and picture of the hardware which is only one switch and one LED. 

Any improving idea would be appreciate it. 

Thank you in advance

A FOR loop that runs as fast as it can is not a timing device in any form. Look in the timing palette instead.

You probably only need to write to a Digital Write port when the value changes. No need to write the same value over and over.

Your code makes little sense. I would recommend to do a few more tutorials, look at the shipping examples, and then design it all as a simple state machine.

See if this can give you some ideas....

There's not much to explain. You can right-click any element and launch the help. Place probes and run in execution highlighting to watch what happens. Do you understand some of it? Do you have a specific question?
