Arduino Example: Simple LED

[Peter-R]

Before opening this example, make sure to install the LabVIEW Interface for Arduino.

Description:

This example shows how to light up an LED using the LabVIEW Interface for Arduino.

Tutorial:

1. Make sure you have installed the LabVIEW Interface for Arduino.
2. Open the Simple LED Example VI (search for "Arduino" in the example finder once the toolkit is installed).
3. On the front panel, select the Arduino digital pin connected to the LED.
4. Build the circuit schematic shown on the block diagram.
5. Connect your Arduino to your PC with a USB cable. Optionally you can specify the COM port associated with your Arduino to the VISA resource terminal of the Init.vi to decrease the time require for LabVIEW to connect to the Arduino.
6. Click Run.

Is there a way to download code to the microcontroller and leave it running without the usb conection. For example the led blinking every 5 seconds without labview connected to it.

[aquila99]

Could you please save the Simple LED Example.vi for Labview 2009?

Thanks!

[Peter-R]

I've uploaded a version of the example saved in LabVIEW 2009. Let me know how that works out!

[aquila99]

thank you! i managed to open it, though i'm still configuring the arduino interface so i don't know if it works!

[Alancl1]

Great job Peter-R.  This should be everyone's first example to build.  The "hello world" example of LabView.   One suggestion that might help someone would be to create the constants on the Initialize, for example which com port to use and which Arduino being used.  That was the only troubles I had, but once I got those settings corrected it worked fine.  Next I added a switch and expanded on this basic building block for the Arduino and LabView.

Thanks for this topic. It helped me a lot to interface Arduino with LabVIEW and test it. But, it took a while for the Arduino to execute LabVIEW front panel's instructions once I run the VI. Once the LED is ON, it obeys the commands given through the VIs. But, If I stop the VI and run it again, it takes a while for the LED to light up. Is there anything I am doing wrong? 

[Chocka]

Baudrate is not specified or defined in the Firmware available on the LIFA folders. Would that be a problem for not successfully communicating with the arduino? Kindly suggest.

Hi

I'm testing LabVIEW interface of arduino with nano ver3.0

Program I made was working and are on same basis like this. But even for simple task like led on/off the program taking about 5 sec.

As I'm usign nano borad. Is it same for all ?

Or I'm doing something wrong ?

[SaidElshayeb]

Cool , it is working very well

i just modified the value with boleen and converted to to 0,1 value. it makes it cool

Another example with a switch on the front panel controlling the LED. http://labviewtest.blogspot.com/

[Peter-R]

Great feedback!

[lvst]

Is there any version that allows changing the intensity of the LED?

Thanks.

[ardje]

hello

i can't get tis thing running on my arduino duemilanove

can you guys help me ?

[teuchter]

No. Labview is controlling the LED so it must be connected to the Arduino, although it is possible to connect wirelessly e.g. bluetooth with a shield.

[teuchter]

By creating a while loop that goes inside the INIT and CLOSE vi's, and deleting the current while loop including it's related stop button, it is possible to change pin and values whilst the VI is running. (Worked for me- sorry about picture -No Snipping Tool in Vista)

[DoctorWho8]

Is there a particular reason why the default Arduino is always the Uno? I don't have one at the moment, and am reluctant to buy one, just because that's the one that's the default. The Mega is also indicated, but I don't need one, and if I did it would be more the ADK kind. The one that's shown with the Atmel 328 indicated, what is it?

And why doesn't the choice of board design stay stored between runs?

[H.L.Valley]

Dear Mr.Peter-R

I did step necessary prccess step by step. But I could not Simple LED, ( I'm pitty,,,,,,)

My arduino is not Uno but Duemilanove/Atmega328. Is not that work?

Could help me?

Tahnk for your help,,

H.L.Valley ( I live in Japan)

[teuchter]

Not looking good for Duemilanove. I tried changing baud rates, etc but it comes up error 5002 incorrect firmware. Labview doesn't like it, the Arduino programme seemed to upload okay.

[teuchter]

Aren't you the happy one. People will respond to positive comments, but you don't actually seem to have an Arduino board of any description so what exactly is the point you are trying to make!

[H.L.Valley]

Dear teucher

I thanks for your respons. And I did not show you my trouble point.

Yes, I received error 5002 form Labview.

Yesterday, I could not sleep in a dream of Arduino and Labview,,,,,,,,,,,

So, I got a Arduino UNO on the way home.

I tried it.  It is running now,,,,

I'm going to check and try to do by the Duemilanove again.

I thnks for your comments again.

All,

Glad to see the discussion and supporting community. I am now based in Boston working with our customers in the northeast and thus do not actively monitor this post. However, you should be aware that there is an Arduino Community (and support forum) here.

Have fun with your respective boards and a great day as well.

[vinay472]

Hi all,, I 'm running simple LED program on arduino uno.. Its giving error 5002. I have set the Baud rate, Com port, firmware installation. Looked into all the forum but no use. Here is the screen shot please help me

[teuchter]

Have you checked baud rate on Labview VISA? I can only assume you are new to LIFA and this is your first program. There is a step by step installation and first program (copy and upload) elsewhere on the forums. Sorry I'm at work and can't really go into it much more at present time.

[Scateman]

Hi everyone, does the example work for the arduino duemilanove or only for uno? Thanks.

How mariano1 said in Feb 21: "Is there a way to download code to the microcontroller and leave it running without the usb conection?"

Is there a way to download code to the microcontroller and leave it running without the usb conection. For example the led blinking every 5 seconds without labview connected to it.

[yanlin007]

nice to meet u all. i am a new user.

i am ok in using arduino uno with labview interface.

To interface with pc and to program, how can i get the driver for arduino nano?

Thank u all my friends.

[hrh1818]

What driver are you referring to and what operating system are you using?

[prodigy]

How do you get to that window that shows you the diagram. It seems to me that it only shows on error, and it is a matter of luck that I get it.

Thanks

[teuchter]

Is the answer really as simple as going to the drop down menu, select WINDOW and show block diagram or use tile if you want to have both on screen.

[soonleja]

Hi, I'm a newbeginner of LIFA.

I have been testing following example led for a few days.

But I have been fighting error code 5002.

I don't know reason to happen.

Plase help me~~~~

[rai.albiruni15]

hello, i'm rai from indonesia, i have project make oximetry based labview. i have some problem with driving sensor spo2 by LIVA. i used sensor spo2 type nellcor. This is my program to driving sensor, can not driving sensor

[abisogno]

hi,

I would to open and close a led for differents seconds.

For example: if I have an array like this T:[0,1,2,0,3,2,0,4,0,4,0,2] where the numbers in the array are the seconds that the led is open. How I can do it?

[divyangkuk10]

I try this program but i did not get output plz any boudy provide arduino code on this email 'divyangkuk10@gmail.com'

[jimmy95a]

Buenas soy nuevo en el tema labview y eso, y tengo un proyecto donde me piden realizar la conversion de Binario a Decimal. Debo ingresar las combinaciones externamentes ya sea pulsadores que conecto a Arduino y este a Labview y en Labview encender un 2 display hechos con leds. Debe reconocer de 0 a 99. Gracias por la ayuda de antemano

[Wick879]

Is there possible way to make this with multiple leds but just with linx or hovi, idk how its called
