Press and delay button with case structure

[sarwatsarfaraz]

In the program attached below, the arm/disarm led will turn on when I press button 2 and will turn off when i press button 3.

This is a prototype program for arming/disarming a vehicle.

I want to modify the program such that when i press button 2/3 for 2 seconds, only then they perform the desired function. if i press for less than 2 seconds, nothing happens.

How can I do that?

There is no program, just two images showing parts of your code…

I recommend to use the event structure in favor of that InputDevice functions.

Then you need to store the timestamp of the "button press" event in a shift register. You can use the timeout event to check for your "minimum 2s delay" and you can also monitor any "button release" events…

You should "filter" your button signal. On the rising edge, you should register the switch time. Then, you continuosly check Tnow - Tswitch.

Have a look to the attached code.

As a first step, you need to define the problem fully. For example what should happen if both buttons are pressed for 2 seconds?

Since you seem to prefer pictures over actual VIs, here's one simple possibility to turn on an LED after the button 2 has been pressed for 2 seconds. No need for local variables and case structures.

You can easily expand it for more buttons and the desired behavior for each once you exactly define the problem.
