Please help me to add a “Device state indicator” for both the assistant.

[iamsujay]

I would like to add a 5volt “Neopixel WS2812B” led strip as a device state indicator for both the assistant.

I don't need any fancy animation. I just want

Alexa on idle> Neopixel off.
Wake word Alexa> Neopixel on.
Alexa thinking> Simple animation.
Alexa speak> Some simple animations.

Same for Google assistant state indicator with the same neopixel led strip.

I have no idea how to do that without any additional boards.

Please help me to solve this issue.
