Using Dial to control case structure

[ebf11]

Create a dial control that goes from 0 to 2, with 3 LED displays:  one green, one yellow and one red.  Have the VI turn the LED green when the dial is on 0, yellow when the dial is on 1 and red when the dial is on 2. 

I have a case structure with numbers 0,1,2, each with an led. I'm getting an error and thinking it is maybe because I am using the dial as a control? I feel as if this should be a straightforward VI to make but am fairly new to Labview. Thanks!

You dial control can have an almost unlimited number of possible values. Make sure that you have a default case that executes when a value occurs that is not mentioned.

This looks like homework, so here are some tips:

• There is a =0 primitive, but you don't even need it because once this case occurs, the value is guaranteed to be zero, right?
• The LED indicator terminals belong after the case structure, else it will not turn off when another case occurs.
• Think of a simpler solution that does not even need a case structure. There are many better alternatives!
• (For example, the three LEDs could be a radio button indicator, now you can just wire the dial to it and the rest will fall into place.)
• You probably need a top-level loop and appropriate wait.
• Notice the red coercion dot? It means your two integers are of different type. Figure out why!
• Start with some basic tutorials or at least look at your class notes.

Appreciate the feedback and will definitely do some tutorials. There sadly has not been any class notes to look at 😞
