Dear Friends,
I am new to LabVIEW.
I would really appreciate if someone could help to complete those simples task.
All the best
Solved! Go to Solution.

So did you already do everything else except point #3? How did that go?
If you are new to LabVIEW, there are great training resources listed on the top of the forum.
We don't solve problems that look like homework, but we are willing to answer specific question if you get stuck.

Dear Altenbach,
Thank you for looking at this.
I am at point 3 now.
Point 3 ask to create VI to acquire the output voltage ? how can I create Wheatstone bridge ? so far as I know is not possible to create such thing on LabVIEW so how I am supposed to create VI to acquire the output voltage.
Thank you

- I used DAQ acquire signals strain and external . But not sure if this right

Re-read your homework description!

Dear GerdW,
Thank you for the support.
I understood the task but the problem I cant connect anything to real PCB everything must be done over LabVIEW.
Best Regards,
Gustavo

You cannot build a real Wheatstone bridge using software like LabVIEW. You need to build that bridge using hardware…
Your homework description doesn't mention to "simulate a Wheatstone bridge"! All it says is "measure the bridge's output voltage"! That's the only thing you need to implement with LabVIEW…
I repeat: "Re-read your homework description!"

Dear GerdW,
Thank you for the support.
A simulated DAQ device can not be the solution ?

A simulated DAQ device is part of the homework (read item 3 and 4!) - and so it is part of your solution!

Dear GerdW,
Thank you for the information.
If understood right even with a simulated DAQ device we still require to have the Wheatstone bridge on a real PCB to capture the output voltage of the bridge to be transferred to LabVIEW right ?

No, with a simulated DAQ device you don't need any real hardware!
All you will get is a simulated voltage signal, looking much like a sine wave…
