// LED indexes into the neopixel powerstick chain for the cyclotron. Each stick has 8 neopixels for a total of
// 16 with an index starting at 0. These offsets are because my powercell window only shows 13 leds. If you can show more
// change the offset index and powercell count to get more or less lit.
const int powercellLedCount = 14; // total number of led's in the animation
const int powercellIndexOffset = 1; // first led offset into the led chain for the animation
My pack I had to set offsets to turn off the first and last leds as they didn't fit in the space.
