Hello,

I'm not that firm in Arduino, in your video (https://www.youtube.com/watch?v=Q5d8gTppuYo) you show different animations. My sphere only shows animation starting at 13:45.

How can i change it? or did i miss something? ;-)

You can select your animation in the loop function:

//animations.StartAnimation(0, 6000, rainbowAnimation);
animations.StartAnimation(0, 2000, raysRainbow);
//animations.StartAnimation(0, 2000, ringsRainbow);
//animations.StartAnimation(0, 500, xmasOrbAnimation);
//animations.StartAnimation(0, 1000, ringAnimation);
//animations.StartAnimation(0, 500, rayAnimation);
//animations.StartAnimation(0, 100, randomAnimation);

just uncomment the one you like :)

hi im new to this but when i put the code in i get tis problem

exit status 1

This report would have more information with

Hi! You need to install neopixel-bus library. https://github.com/Makuna/NeoPixelBus

I can write a simple platformio config for you.

This allows people to build the software without bothering about what libraries to install first, what target to select, board packages, etc.
The platformio config file specifies all of this (including a specific version if necessary), and allows building it all from the command line, so you can even do continuous integration (e.g. a test build every time you commit a change).

If you're interested, please let me know.

Hey there, did you take the neo-sphere off github? can't find it anymore. Would be very interested in a platformio config! :-) kind regards Jens Am Mo., 3. Mai 2021 um 13:33 Uhr schrieb Bertrik Sikken < ***@***.***>:

I will create a project https://github.com/bertrik/neo-sphere maybe later tonight, with a copy of this ino file and a platformio configuration.

thank you very much! :-) @jpraus: are you currently working on improvements? :-) Am Di., 4. Mai 2021 um 10:19 Uhr schrieb Bertrik Sikken < ***@***.***>:

Nope, no improvements to the neosphere project so far.

The arduino source with added platformio config is available on:
https://github.com/bertrik/neo-sphere

You can use it as follows;

• install python3 and install platformio, e.g. sudo pip install platformio
• run platformio to compile and upload: pio run -t upload

I might make the 'upload' action the default target, so you can just run 'pio run'.

Hi, i made the sphere and i saw that the program works with maximum 254 leds and i want to make it to work with 384 leds and 15 rings.
Can you please help me relating to this matter ?
