Hi Guys! Does anyone know how I can make my code simple? (See attached code)

My goal is to turn LED ON and OFF automatically every time I change the number in the input field (CONTROL).

I mean I am able to do it with my code. I kind of feel like there has to be a simple way to do this. 

Can you please share your code or idea?

P.S: If you think the way I do this is the best and simplest way, let me know too. 

Thanks!

See attached VI.

P.S: Event structure is excluded.

As always, your code is just plain silly!

• Having a hidden array control to serve as an empty array is pointless
• inserting a scalar into a empty array, then indexing out that element just returns the original value? Why all that extra code?
• Your local variables are read way before the terminals are written, they will most likely always be equal. Race condition!
• How are you planning to ever stop the loop?
• ...

What does that even mean?

• Change the LED to the opposite whenever the value changes?
• Change the LED to TRUE for a limited amount of time for every change in the control? For how long?

If you look in the comparison palette, there is this function. You could use it.

(NOTE: It will also trigger on first call).

Alternatively, you could make your own, e.g. as follows:

(NOTE: This will not trigger on first call)

Thanks Mr. Altenbach for the feedback. This will help me work hard on improving my code and understanding better what I am doing.

This is so simple. I think so hard for no reason. smh
