Triggering led

[Nadjil]

I am new with LabView. I am working on project to control triggering of Led.

First I want to build a trigger mechanism for Led using LabView, then testing it if I can trigger my experiment.

Any suggestion or tips how to start or to build it?

This depends on the device you are involved with. Please post the devices you are working with.

Also, since you are a newbie, one advice is to spell LabVIEW correctly, a lot more people will take you seriously then.

Thank you for your reply and your advice.

First; I want make program with LabVIEW a controller to control a Led to trigger a PPU of MR. I want to control this Led, continuous or using a puls to trigger the Led. I am watching a lot of Lectures on LabVIEW but still need to learn a lot about it.

Is there a function that generate a puls or continuous signal in LabVIEW?

If I want to connect the Leb to the software what do I need? Can I use USB port or special device from NI?

Second; is there a function to save or recording the signal, then apply it agin? This part will come later in my project.

Kind regards,

Nadjil

The above link concerns a RT target and contains an example.

if you are using a microcontroller like Arduino, this link https://forums.ni.com/t5/LabVIEW-Interface-for-Arduino/Arduino-Example-Simple-LED/ta-p/3522414

There are many examples for continuous or Pulse generation. Look at the examples or try here for various examples for vi's https://www.ni.com/docs/en-US/bundle/labview-api-ref/page/menus/categories/signal-processing/ansigge...

There are number of ways to connect to a LED, such as USB or if you a hardware such as the PXI. However, if you just want to do this project, there is no point buying a PXI. 

If you are using USB, you need to install the appropriate driver for the concerned USB. 

The seconf part, you can deal with later once you have communication to the LED.

I will use the USB port first, I didn't do that before. What do I need to do it? Devices or material, I am really new with LabVIEW and working with these kind of projects.

Nadjil,

Do you currently have any NI hardware?

Here are some devices https://www.ni.com/en/shop/data-acquisition.html

Have a look through it too see if there is a device that you particularly want or is suited for your application. If you are not sure, the best way is to contact NI and ask them directly. They would recommend the best device based on your needs. Once you have the hardware in place, you should read upon how to control your hardware and then program. 

If then, you have specific problems, post here with your issues and some one will surely help you.
