Ah. Yes, the core Arduino library gives you a level of abstraction over the I/O capabilities of the mCU so that it works the same regardless of the actual hardware. The CircuitPlayground gives you another layer specific to that board, with the goal of making it easier to use. Using both layers of abstraction in a piece of code can be confusing.

Re: How to address pins on Circuit Express with Arduino
About a month and a week has passed now since the last post, and after lots of angst, a fair amount of swearing, and a bit of soldering, I am happy to report that two electric belts for a hoop artist have been completed in time for the New Year's Eve performance.
The belts each have two rows of 13 WS2812 RGB LEDs controlled by an Adafruit Circuit Playground Express.
The system is powered by 4.8 volts supplied by four AAA rechargeable NiMh batteries which provide a run time of three and a half hours.
It's a Happy New Year.
