Tu use a neopixel you need a dedicated arduino. A small one , Arduino Nano or promini is enough.

You have 2 options to connect this 3rd arduino , Using RX/TX pin or direct USB

Setup:

  • Using usb cable

1: Plug Neopixel wires like this ( you can use optional 1000 µF, 6.3V capacitor ) :
neopixel arduino
2: Upload MRLcomm Inside the dedicated arduino
3: Activate Neopixel Inside services/neopixel.config like this
( change of course NeopixelMasterPort=COM5 and pin=2 to Your values )

[MAIN]
isNeopixelActivated=1
NeopixelMasterPort=COM5

[NEOPIXEL]
pin=2
numberOfPixel=16

  • Using RX/TX connection

It is usefull if you don't have enough usb port

1: you need to connect arduino slave to arduino master like this
neopixel arduino
2: Upload MRLcomm Inside the dedicated arduino
3: Activate Neopixel Inside services/neopixel.config like this
( change of course NeopixelMaster=left/right and pin=2 to Your values ) For information Serial2 ( RX2/TX2 ) is case sensitive

[MAIN]
isNeopixelActivated=1
NeopixelMasterPort=Serial2
NeopixelMaster=left

[NEOPIXEL]
pin=2
numberOfPixel=16
