Help with LabVIEW Basics

[pareod]

Hey guys,

I'm in a hardware class and I need some help.  We use Multisim to create circuit schematics, but I mentioned to my professor that I used LabVIEW in a robotics club.  Now he wants to to write the same tutorial we used for Multisim, but for LabVIEW.  The tutorial is pretty simple, but I'm having trouble finding some components.  I need to find power supplies (mainly VCC), switches, a logic analyzer, and a word generator.  Any ideas?

Thanks.

LabVIEW is a programming environment, not a circuit design tool. It is not clear what you are trying to do here.

I am aware.  I am supposed to do something as simple as turn on an LED with a switch that is connected to a power supply.  There are waveform analyzers here for other parts of the tutorial I am writing, but I can't find certain parts.

Hi pareod,

I am supposed to do something as simple as turn on an LED with a switch that is connected to a power supply.

You will need:

- a power supply

- a switch (relais, MOSFET, …)

- a LED

- some hardware to drive your switch

- hardware drivers for your hardware

- a LabVIEW VI that calls that hardware driver

Or do you just want to "simulate" all this? Use a button and a LED from the boolean elements palette and connect them…

As this is the very first example you will most often see for LabVIEW: take the free online courses offered by NI on their website!

I'm trying to simulate everything.  Is there no power supply from Controls?

Hi pareod,

why would you need a "power supply" in a programming language? Have you ever needed a "power supply" in C(++|#)/Pascal/BASIC/JAVA/whatever?

Do the LabVIEW beginner courses when you want to write a manual about LabVIEW…

The 'power supply' would just be a numeric control on the front panel and your switch could be a customized dial if you want it to look like an actual switch. Basic logic on the block diagram. Silly to look for a power supply on the functions palette.

Actually, I think the "power supply" can just be a boolean control here.

Oh, and here are plenty of tutorials that should show you want you want to do.

If you just need a 5V "power supply", use a numeric diagram constant with a value of 5. 😄
