How to make Animated Fan Speed Control in LabVIEW

[@robotbender8271]

I made an animated fan like 10 years ago and in a much simpler way. Ready? While Loop with shift register, wire a Boolean "Not" inline with that shift register, add whatever time delays to make this flip 0-1 faster or slower as your like. Now simply drop a boolen indicator on the front panel and change the OFF decal to an image of a fan blade and change the ON decal to that same image rotated 90 degrees. Connect that indicator to show the status of the shift register. Done

Care to post a video ?

Great video. Will you pls give a link for downloading these fan pictures.

[@LabVIEWADVANTAGE]

You can download gif image using google and modify using image editing software. unfortunately it is no longer available with us.

what software is that? Also, what are the compatibility requirements for the hardware?

[@Born2be2good4u]

The Software is named LabVIEW and especially made for hardware integration. The target group are engineers with small to none programming background.

[@oldbloke135]

Although you have 12 fan pictures you have configured them as 12 pictures per 360 deg. rotation. For a four bladed fan you obviously only need to spread your animation over 90 deg. after which it repeats. I would suggest four images at 0, 22, 45 and 67 deg. PS. I think calling this a fan speed control will confuse LabVIEW beginners, since this is an indicator!

Could you please make a video about how to control a real computer fan’s speed? Thank you so much!

[@fazz8823]

Hi, how can you reverse the direction of rotation for the animation please? hope to hear from you soon.

[@LabVIEWADVANTAGE]

Reverse the count value

please i need help , im making project of fan with LM335 and using daq 6009 , the tempreture is changing but the fan is not functioning so i need full circuit of fan with lm35 and labview software please thanks alot

[@HomoSapiensMember]

How would you reduce the flicker effect of the ring cycling through the 12 fan pictures? Would using the timing vi "wait until next ms multiple" help more in this situation?

[@HomoSapiensMember]

or was that just the fact there are only 12 frames in use whereas the eye perceives 24 fps as smooth image? I cannot tell between one and another cause in this case: is it a memory call problem, a timing problem or a frame cap problem (do we just need more images)?

[@HomoSapiensMember]

must be a combination of all these factors... (: thanks for the video!

[@LabVIEWADVANTAGE]

+Count Agava Dear Count Agava, yes you are right to show smooth image the fps should be at least 24. But if you are writing a LabVIEW code and want it to be responsive, the recommended loop rate is 10 times a second.

[@HomoSapiensMember]

Thank you for replying! At the mentioned 10 Hz loop rate, the animated fan appears as though it flickers - to a user, but the program is indeed more responsive to input. Alright, I'll try do figure out how I would make the thing responsive and pleasantly smooth at the same time. I suppose its possible then to wire controls for the program from a master while loop and run the animation loop in the slave config. As such, the timing function and the control scheme for (at the very least) halting the programme would be separate. Perhaps this would allow for a greater number of looped frames per second thus a smoother image transition as well. I shall try to test for this. But I still wonder and I want to research this in more detail, how the picture ring enum works. Are the images stored in memory or does the enum access them from a drive directly for each poll? I will try to find answers to all these questions on my own, I hope the LV documentation has all the answers. On a side note, I have recently passed the clad exam! I've studied your prep videos and several hands on projects you demonstrated. Thank you, sir! It was a fantastic experience, having passed this first exam.

how can we find which integer correspond to particular image??

connect numeric indicator

plz suggest me from where i can download animated images for dice applicaton and fan controller. anyways thanks a lot

why not using random number generator VI rather than quotion rem ?

please any one give the fan image file

[@LabVIEWADVANTAGE]

you can google for it.

[@karthikeyan451]

how can I search it? There are many things are available. particularly get the same image how sir?? you send the website link pls...

[@LabVIEWADVANTAGE]

search for fan png image. use a image editing software like photoshop to create 12 frames of rotation.

[@karthikeyan451]

Thanks

is it so hard just to share fans images from the video and uploaded here? so stingy AF
