Need Help Creating a Student Attendance VI

Sounds like a sketchy attendance counter.  I'd just pay my buddy to push my button for me.  You probably should use a retinal scanner instead.  Smiley Very Happy

 

Sounds like an easy assignment.  However, I cannot open 2018 files to see what you have written so far.

Start with a piece of paper and write down the steps.  Create a flowchart of how your program should work.

 

One key feature your VI is missing is a while loop that keeps things running.  You will probably want an event structure that acts on events such as the value change of a button.

 

I would recommend looking at the online LabVIEW tutorials

I saved it as a previous version for you. If you could show me how to make it read the data and count the missed days that would be awesome. This is the only thing stopping me from continuing my class project.

In order to count the missed days, you will need some way to know how many days the class assembled.  For instance, the teacher is there every day.  Is the teacher required to press a button or could that be added as a requirement?  If so, compare each student attendance to the teachers attendance and count it up.

 

I would recommend that you learn about state machines and event structures, as has already been mentioned.  This will give your code a foundation to build on rather than just having a bunch of random loops on you block diagram.

Why did you create a new topic on this when you already have one posted?

I am trying to get this to work, but I cannot make it work. Could you modify my VI for me?

Hi bjb,

 

as has been said before: we will not do your homework!

 

I am trying to get this to work, but I cannot make it work.

Attachy our VI, even when it doesn't work.

Explain where you fail. Explain what you want to achieve.

Ask specific questions…

 

Could you modify my VI for me? 

Well, we could - but that is not the purpose of your homework!

Best regards,
GerdW
