How-To NeoPixels

Setup the Lights

First, you need light sources. In this example, we’ll get two NeoPixel chains


neoPixA = caernarfon.pixels 
neoPixB = caernarfon.initNeoPixOnServo(3,neoPixelCount=35)

Next, you setup up groups within your light sources to match the physical layout of your LED chains


firstTwoOnPixA       = neoPixA.nextNLights(2)  # this will be leds 0 and 1 on the neoPixA chain
leftStoneLights      = neoPixA.ring(3) # this will be the next three : 2-4
centerStoneLights    = neoPixA.ring(7) # this will be the next seven : 5-11
 
sceneIndicatorLights = neoPixB.stick(8) # this will be leds 0-7 the neoPixB chain
angleGaugeLights     = neoPixB.ring(12) # this will be leds 8-19 onneoPixB
