HELLO,

You have wired two incompatible data types to your >= function.  You are comparing an errror cluster to a value so it won't compile; you need to wire the Light Intensity instead.

More information about error cluster here.

If you are new to LabVIEW I would recommend spending some time leaning the basics. It will save you much time in the long run

First.  Please check your CAPS LOCK key.  It seems to be stuck on.

Second, Lewis's e-mail is pretty clear on what you need to fix.  You can't compare whether and error cluster is >=0.  If you wire in the light intensity wire instead of the error wire, you won't have a broken wiring connection.

Caps Lock is cruise control for cool.

thanks a lot everybody the VI is running smoothly was wondering to add an acknowledgement button for the LED ie. the LED sops glowing when the button is pressed would appreciate if someone can help me with that with warm regards Jalashwa

HELLO,

You could wire your button to a Select Function, along with a Boolean constant and the result of your comparison function.

You could have answered this yourself if you had looked at the training material i suggested...
