Aquí os dejo también un boceto que me hice para calcular el cambio de coordenadas para los LEDS.
Un saludo.
// NeoPixelTest
// This example will cycle between showing four pixels as Red, Green, Blue, White
// and then showing those pixels as Black.

// Included but commented out are examples of configuring a NeoPixelBus for
// different color order including an extra white channel, different data speeds, and
// for Esp8266 different methods to send the data.
// NOTE: You will need to make sure to pick the one for your platform
//
