need help writing Arduino sketch for Nano to Adafruit FX mini soundboard communications?

Hello everyone.  I am new here, and fairly new to arduino. Im an electrician/ communications tech by trade, but have only been working with code as a hobby for a few weeks (have wanted to learn this for a long time).  I am working on a project that would require an Motion sensor input to play an audio track at random, whilst illuminating a corresponding PWM LED. said LED should fade in sync with the audio file.
ITs a robot of sorts that will detect movement and speak a random audio track.  Some nice (0-5) and some not so nice (6-12).  it will have a a diffused glow when on, blue when speaking nice, and red when speaking not so nice.  hence the audio input to act as an anologRead and output to the PWM's

I know, a lot to take on for a noob.  but go big or go home.  I have put together what I thought was a good start sketch, but it doesnt even illuminate an LED, communicate with the soundboard, or serial link on the monitor.

I think I am on the right track in regards to the parts and overall Idea.  And im pretty sure my sketch needs a lot of work, but i am trying.

so here are the parts I had intended to use. (if im going down the wrong path, or you see another way, feel free to say so.  I expect some criticism, I can handle it)

Arduino elegoo Nano V3.0, CH340/ATmega328p
Adafruit Audio FX Mini soundboard w/o amp
Adafruit Mono 2.5W Class D amplifier (PAM8302)
Sodial mini IR motion sensor module, 3-pin
LED's are undecided for finished product, but i was thinking RGB 6302's (5-7)
speaker is an 8 ohm 2W
power will be supplied by a small 3.7v lipo (thats the plan)

My wiring idea should be easily discernible from the sketch, but i can draw my idea, and add it if need be.

I did install the soundboard _library. but thats the only one (didnt think i needed others)

Any and ALL help is greatly appreciated.

the sketch...
