Thank you. I’m going to put this on the edge of some wheels to give the appearance of the wheels moving clockwise on a little Outdoors Christmas Train decoration.

[@Electriangle]

Sounds like a neat idea! My computer fans have an animation similar to this one where it's going around clockwise to simulate a spinning effect. It does look good. Have fun with the project 😀.

You never fail to impress 😍😍

how i can make an emoji face in this pattern?

[@Electriangle]

I'm not sure how it would be made as an emoji face using a 1D strip... Are you working with a 2D LED matrix panel? Or wrapping the LEDs in a circle? I imagine this animation could work good for a circle ring of LEDs as a loading symbol or a spinning wheel effect.

Very cool, thank you! I was wondering, what material did you use for the diffusion?

[@Electriangle]

For these FastLED demo videos, I've been using a large plastic diffusion sheet that I had pulled from a broken TV. I try to pull out the diffusion sheets when I see a TV being thrown away. They are not always as nice as this one, but when they are, they can be a good way to get a free diffusion sheet for DIY projects.

Is it possible to combine animations? Could you have this but with a rainbow cycle as well?
Working on my first individually addressable project and would really appreciate any advice.

[@Electriangle]

Yes, do you mean combine them into one Arduino sketch to switch between them? I decided to format the code for these videos so that the animations can be activated simply by calling a single function. So, depending on your project, if you want to use a button to switch between them or switch after a certain time limit, you will be able to add that into the loop() of the Main sketch and call the rainbowCycle() or ShootingStar() function based on a conditional statement. Just download and put both the Shooting_Star_Animation.ino and the RainbowCycle_Animation.ino files in the same Arduino folder together and each function can be called within the Main sketch.

👍👍👍

[@rosbob7819]

wonderful, can i ask if it's possible to recreate the spark fire effects with these leds, you know like exploding in beams independently, i've seen the effect in some lasers, i've thought of using paint maybe, any info is appreciated thanks

[@rosbob7819]

sry i figured it out, it would br the same way ur using these lights with ledfx could do the same effect!! just need to bubble them or do a line with a buble in the tip or something, thanks for the idea!

[@Electriangle]

@@rosbob7819 I'm not familiar with ledfx, but it does look really interesting from what I see online. I may decide to look into that for a future project.

Great animation! I was wondering how to reverse the animation.... could you help in that?

[@Electriangle]

Hi. Reversing the animation is a simple change. The change would be to put "NUM_LEDS" in the .setRGB() method index and subtract the incrementing count value from it. So, for this line 19 in the code under the Shooting_Star_Animation tab, it would be changed to this:
leds[NUM_LEDS - (count % (NUM_LEDS+1))].setRGB(red, green, blue);
I can update the source code on GitHub to include this feature with a reverse option. Let me know if you still need clarification here.
Edit: I have updated the source code on GitHub to include an option for reversing the direction of the shooting star animation.

This seems faster than I can animate my WS2813 on raspberryPi....

[@Electriangle]

I haven't used the WS2813 version before. But I know that Raspberry Pi has significantly more processing power than an Arduino. Also the FastLED library can support WS2813 based on the documentation by defining it in the FastLED setup line of code. So may be worth a try.

[@lifebarier]

@@Electriangle After digging it seems that it is hardware limitation of leds and not python/RPi speed problems( ? ). I can only push 40fps on 144led strip. I am planning of getting andruino with that library to test though.
