Timed Pulse

[JB34]

I have a simple problem. I want to create a VI in which I will click a button which will turn on an LED for 5 seconds and then turn it off. What is the simplest way to do this?

JB34,

How accurate does the 5 seconds need to be?  What kind of hardware are you using to drive the LED?

[JB34]

Software timing is fine. The LED need not be hardware, I was asking about a simple front panel LED.

Hi JB34,

I attached a program which uses an event structure to detect the button push.  There is a sequence structure, including a 5000 ms delay, that changes the LED value.  The time stamps are just a reference for you to verify that five seconds elapsed.

Hi Jennifer,

Can you please send your attached VI (LED) for Labview 8?

Hi Siamak,

Here is the VI for LabVIEW 8.0.  If you have any questions about the code, please ask.
