Embassy provides some traits, but it's pretty much expected you'll be using traits from embedded-hal (both 0.2 and 1.0).

  IMO one of the big reasons Arduino stayed firmly hobbyist tier is because
  it was almost entirely stuck in a single-threaded blocking mindset and'
  everything kind of fell apart as soon as you had to do two things at once.

I think Arduino also suffered because they picked some super capable ARM chips and weren't really prepared to support people migrating away from AVR. Even the Uno R4 is obscenely complex.

Conversely Embassy suffers from being immature with some traits that haven't really been fleshed out sufficiently.
