About the FastLED Archive category

For folks using the FastLED library please join us at reddit.com/r/FastLED.

The posts here are an archive of FastLED discussion from Google+ — please have new conversations at reddit. New posts in this category are closed.

The FastLED community is a place to discuss what you are working on, get help, share code, find information about updates, etc… You can also visit the library home at http://fastled.io/

We encourage you to read the FAQ before you post.

If you are asking for help, please include the following:

  • What type of LEDs and what microcontroller you are using
  • Upload code to either pastebin.com or gist.github.com and share the link
  • What version of the library you are using
  • What version of arduino you are building with (and what additions have you installed to arduino, e.g. teensy, etc…)
  • What OS you are building from (linux, mac, windows, something else)


After G+ shut down the FastLED group moved to Reddit. If you are using the FastLED library please join us at https://www.reddit.com/r/FastLED/ to ask questions and share what you are working on. You can also visit http://fastled.io/ for links to the wiki, code, community, etc.

99% of the posts here at Maker Forums in the FastLED category are an archive of the G+ posts. Thank you to Maker Forums and @mcdanlj for helping making this archive possible! It really is great to be able to go back and search out something here now and then.
