Case selector and traffic lights

[nevica]

Hello,

Need some help with some code.

I want to be able to indicate on the front panel with a traffic light system the stability of a light source.

The stability can be defined as:

1. Not stable -                              value = 0.3 - 2

2. Partially Stable -                      value = 0.001 - 0.3

3. Stable -                                     value = 0.000001 - 0.001

Is there a way of using an 'index array' to carry this out instead of a state machine to carry this out.

You could populate a numeric array with the threshold values for the three ranges, and use the built-in threshold VI to find out where your input value falls in the range.

Hi Mike,

Ok, found the threshold .vi. Thanks.

Array palette, 3rd row, 2nd one in. Try out the palette search function, it is a great help.

And yes a numeric array in ascending order numerically. Also don't forget to include as your first element in the array a 0.

You can use Threshold 1D Array.  See attachement.

Hi Paul,

Thanks, that solved my problem. How did you create the traffic lights on the front panel please?
