Understanding code libraries for Arduino programming

As Becky Stern says in the introduction to her latest With Becky Stern video for Digi-Key, 'one of the Arduino community's superpowers is code libraries: bundles of specialized programming that allow you to leverage complex computing tools using simple commands.' You can use these add-on libraries in your Arduino code to do things like control strips of LEDs, read sensors, and create sounds. — Read the rest
