control the flow of water and stop it when i reach a defined value

[Gquadro]

Hy guys,

I would like to build a system with arduino or raspberry that control the flow of the water and stop it with a valve when the system reach the value fixed by the user.

is there someone that could help me? i'm starting with the imput of the value defined by the user but i don't know how to continue.

thanks a lot!

Your VI doesn't show anything related to control water flow or valves or stops or comparing to values.

It is just a string indicator and a bunch of numerically named boolean buttons.

Compare one value to another is a simple comparison.  Look in the Comparison palette.

I would recommend looking at the online LabVIEW tutorials
LabVIEW Introduction Course - Three Hours
Learn LabVIEW

thanks a lot.

but, before reach this point i would like that the user choose the number of litres.

i don't know how to proceed.

could you help me?

Users control things in a program through front panel "controls".

Considering the dozens of messages you have posted on the forums so far, it really puzzles me that you are stuck on a LabVIEW concept that is certainly covered in one of of the first lessons of a LabVIEW tutorial.

I normally prefer to help people figure things out for themselves, but I'm just going to give you this one because it is so simple I can program it faster than I can type it.
