/*
 * 3 DMX controlled LED Par Light example
 * 
 * In this example we're using 3 par lights model Chauvet DJ Eve P-130 RGB
 * Each light can have up to 9 DMX channels to control different
 * functionality of the light. For an overview of the channels
 * look at https://open-fixture-library.org/chauvet-dj/eve-p-130-rgb
 * 
 * For this example the lights should be set to 9 channel DMX mode
 * on the light itself. And, light1 should start at DMX channel 1,
