Prerequisite guides
Before you begin, familiarize yourself with the following tutorials:
Adafruit Circuit Playground Express (https://adafru.it/adafruit-cpx)
Getting Started with FLORA (https://adafru.it/dwi)
Introducing GEMMA (https://adafru.it/dgH)
NeoPixel Uberguide (https://adafru.it/dhw)
Conductive Thread (https://adafru.it/dn3)
Lots of Pixels?
Each pixel draws as much as 60mA (all three RGB LEDs on for full brightness white). In theory, FLORA can drive up to
500 pixels at 30 FPS (above which it will run out of RAM). Circuit Playground Express can drive more than that.
However, above about 20 pixels (and/or if the overall length of conductive thread exceeds ~6 feet/2 meters), the
nontrivial resistance of the thread adds up and can affect the power supply. For large quantities of pixels over 20 or if
you need to insulate your circuit, you should upgrade to silicone coated stranded core
wire (https://adafru.it/Cc0), which will provide better conductivity for the pixels - the current draw will add up fast!
This tutorial will cover the current v2 pixels as well as the older v1 pixels. The sewing part is the same for both
versions, but the library code is different because the controlling chipset has been upgraded in v2. Pixels
purchased after February 2013 are v2.
