Hello,

you can use a property node to change the colour of your LED programmatically.

On the block diagramm right click the LED and choose create->property node->Colors[4].

Hope this helps.

Thx Uli, i had try your vi that u gave me, but i still confusing the vi, because there is a array which can choose 4 colours in a indicator, but i need 1 colour in 1 indicator only.

actually im doing a small assignment that i detecting temperature using DAQ and output is show LED indicator, the indicator is showing atleast 7 colours in 1 indicator only, i.e. 30C ~ 39C is blue colour, 40c ~ 49C is green colour, 50C ~ 59C is yellow colour, 60C above is red colour. most important is i need 1 indicator show different colour more then 2 colours. hope Uli or everyone can help me.

Hi there,

I had the same problem once, but only for tristate control. here is the URL to the thread that spoke about it:

You can probably edit this control to add more states. 

Another option could be to use a 3d control and to limit it's x and y values to a 1x1array. (x=0,y=0,z=your value) 

I hope this helps

Take a look at the picture ring. You can paste a LED picture for every color you need.

Hello,

don`t mind the 4 colors. Look at the context help, they are for the states of the LED. I think you don't need them.

 

I attached a simple example how you can vary the color of a LED.

Hope this helps.

Hi Ulib,

In your VI, you miss some value between each case. It's better to use this VI.

 at Young Hoe,

if you don't know something about a function or property, use context help (ctrl+h).

Hello Aurélien J.,

can you please save your VI for a previous version of LabVIEW, I don't have LabVIEW 8.6, and can you explain why I miss some values?

Hello,

After saw all the thread, now i know how to make it already, thx Uli and ajangot. Have a nice day^^ 

[ajangot]

I save it in labview 8.0.

If the temp is 20.5°C, you don't have case for this. it will be better if you use comparative block, every value is in a case.

Best Regards
