I am building traffic light and pedestrian light system. My switch button isn't functioning in my NI ELVIS II+

My problem is stated as the subject above. However when I click run button in block diagram, the LED automatically runs and the switch button isn't functioning. Can you help me to check my Front Panel whether is there something wrong with my structure? Really much appreciated.

I guess you should probably attach your VI.

Sorry I forgot about the attachement 🙂

Below attachement are:

1. Case Structure - My NI ELVIS run able to read and run, but the fucntion of push button isn't fucntion as anything.

2. Flat casing - Ni ELVIS unable to detect anything even I already used DAQ for reading. But I want the squence to run somehing like this.

Why is your button's mechanical action Switch Until Released.  It just seems wrong.  You probably should have it as Latch WHEN Released.

Oh okay, because I just try and error and the others component are okay?

I will try this during my lab clasa again.

Thanks for the help.

Hi, I already tried but it make no difference for the mechanical action from Switch until realesed to Latch until realesed.

Still the button is not function as what I imagined.

The condition are:
1. Initial: Car traffic light   - Green, Predestiran light - Red

2. Press the push button:
Car traffic light - Yellow , Predestrian light - Red

3.After several seconds:

Car traffic light - Red, Predestrian light - Green

4. It return to the initial condition.

By the way, the NI ELVIS that I build are based on the picture below.

I don't have 2014 here, so I can't see your code.  But, why are you trying to do everything at once?  It's hard to determine if your code or your circuit is the problem that way.

Take a step back.  Instead of hardware, use LEDs on your LabVIEW Front Panel.  Ensure they light up as you expect.  If they are, you know your algorithm is good.  With a second program, ensure you can turn an actual LED on and off.  When you have those two pieces, you should be able to merge the system pretty easily.  Don't make things harder on yourself

Thank you for your sugession.

However those condition are provided by my instructor.

Is part of my lab assignment that I need to hand in soon.

Since he also not sure about this solution, so I am trying to search for an alternative by posting this question here rather than keep trying without any clues.

No harm to share and I also a beginner in this software.

Started to like this program. 🙂

I wish you could have come to us earlier in the development of the application.  😞

Anyway Mr Bill, do you have any ideas or suggestion to imrove this condition?
