 For basic applications, the Sled struct gives you plenty of power. Odds are though, you'll want to create more advanced effects that might be time or user-input driven. A few optional (enabled by default, opt-out by disabling their compiler features) tools are provided to streamline that process.

 Spatial LED is now usable in `no_std` environments as of 0.2.0 (though `alloc` is still required), thanks to some [awesome contributions](https://github.com/DavJCosby/sled/pull/86) by [Claudio Mattera](https://github.com/claudiomattera).
 
 To do this, disable the `std` flag and enable the `libm` flag (for use by glam and palette).

 ## Schedulers
 Similarly, the default Scheduler relies on Instants, as well as methods only available through the standard library to handle sleeping. Thus, to build a Scheduler in `no_std` environments, you'll need to provide custom implementations of the `spatial_led::time::Instant` and `spatial_led::time::Sleeper` traits.

  ## Feedback and Contributions
  The author of this crate does not own any hardware that would allow him test `spatial_led` on real `no_std` environments, so bug reports and PRs are very appreciated!
