Light multiple leds

[steggets]

Hello,

I am trying to write a VI where a dial controls how many leds are lit up at a time. For example if dial is set to 2 then 2 leds are lit up. I have attached my VI as it sits now. I am unsure how to go about this anymore since i couldnt get the case structure to work, unless i just don't know what I'm missing or need.

Thanks!

Nevermind figured it out.

No, you only attached a picture. Please attach the actual VI.

Since you cannot light a fractional number of LEDs, the control should probably be an interger. I would also use an array of LEDs, much simpler! You also need to slow down your loop. Currently it spins millions of times per second. You also don't need a case structure.

Try it!

Don't know how to use arrays otherwise I would!

Do you want to learn how to use arrays?  Try them, you'll like them. 🙂

Or convert the numeric control value directly to an array indicator:
