Traffic Light with Walk Sign
Look up state machine architecture for ideas.
Search for "traffic light" as this is a common exercise that others have done.
The idea is you have one while loop. It will execute frequently.
In it you have shift register that keeps track of your current "state". That means what mode of the traffic light you are in. That should be a type defined enum.
The value of that enum drives a case structure that tells which lights are on and which are off.
For the lights that blink, you need to also tell when the light is "on", whether is has blinked on or off.
If you used an elapsed time express VI set for a second, you can use the "Has Elapsed" output to toggle a boolean to tell whether the Don't Walk sign is lit or unlit.
Here is an example for one piece of code for one Don't Walk Sign.
The while loop here is the master while loop, so other pieces of code would be inside the same while loop.
Your VI is completely constipated with long inner delays preventing you big loop from spinning. As has been said, you need one toplevel loop that spins at regular intervals, a state machine architecture and something that keeps state time.
I actually recommend to stay away from the "elapsed time" express VI. It's too much for such a simple task.
Have a look at my old example and use it as a starting point. First try to fully understand it, then expand. All you need are more signals, durations, and states. (You don't need more loops, more case structures, and more other stuff!). Blinking can be implemented as relatively rapid state changes, no need for properties.
