Blink LED using property node

Hello,
How do you use property node to make an led blink?
Thanks

Right click on the boolean in the block diagram, select create - property node. Move mouse to newly created property node and use the hand tool (pointing finger), left click and choose Blinking. Right click on the Blinking property node and choose Change All to Write or Change to Write. Wire a boolean True constant into the property node. This will cause the LED to blink. Wiring a False into the property node will stop the blinking.

tbob is right but take note that blinking is very different than cycling between true and false states. The blink color will be different as well.

First u have to wire true to the blink property node to make it start blinking, just before u start the 1st while loop.

Also what is the mechanical action of ur start button?

Use false constant to stop LED blinking

In the Blink.vi example provided by Kekin, the start and stop buttons are latched type.  The Boolean LED is an indicator and it does not have any mechanical action.  Latch action can only be applied to controls, not to indicators.
