does anybody have a idea how to create an automatic booleon switch? I want it to switch on and off every 20 seconds

Hi Jack,

-create a while loop with a shift register
- init the shift register with a FALSE constant
- wire from left SR to right SR, insert a NOT function in the wire
- create an indicator for the wire
- place a delay function in the loop, wire 20000 to it

Ready...

Jack,

Are you trying to actually move a switch control, or are are just needing a 50% duty .05Hz signal?

Do you need it to run inside another process and not hog all the vi's resources?

I have another question. I have 2 loops in my program and I want 1 loop to have a time delay. What i mean is 1 loops is executed and the other is executed after a specific time. I tried the time delay vi and its not working. any ideas? I really need this program running by friday so that i can conduct the test on the weekend and this problem is my only obstacle. Hope to get a reply as soon as possible

How is your program not working?

Post your VI so we can see what you are trying to do.

I have attached the program. The bottom loop should be executed after the 1st loop

Hi jackofall...,

therefore connect the second loop with a wire from the first loop.
