Keypad Lock in Labview

[michaelkeane24]

Hello Sir, I have a project about checking password using keypad lock and arduino uno board. I want to use LabVIEW to simulate it with LINX, but I don't know to get password from keypad lock to LabVIEW, I hope someone can help me, thanks.

Mind to share information on the kind of error?

Why are your array constants set to show the 4th element?

Why don't you cleanup your block diagram?

I'm sorry, I forgot to clean up block diagram, when I run this and click keypad 4x4 which connected with arduino uno, boolean in array indicator in this vi is randomly turned on

Array constants is channel that connected with my arduino uno board Sir.

And keypad 4x4

So there is no error, just unexpected data? Why do yoou call this an "error"?

How should we debug that without having access to your hardware?

Btw. no need to post 3 messages within minutes: you can edit your own message within a period of 20 minutes or so…

I have been connected with my microcontroller Arduino UNO Sir. Error that I mean is boolean array indicator that randomly turned on with or without click keypad 4x4 which connected with Arduino UNO board.

So, my question is how to make keypad 4x4 in Arduino control boolean array indicator? My vi is not working.

Okay Sir

My hardware like in this picture.
