How do I connect a 12v rechargeable battery pack to an Arduino UNO to a LED strip? (New to electronics)

[o.davis21]

Howdy! So I am building a Viking shield with a cut-out of Jömungandr on the front face of it. I want to have Jömungandr light up like a progress bar each time the shield is hit. I am going to use contact microphones on the shield instead of touch sensors/pressure sensors. I was advised to use a 12v Li-ion rechargeable battery pack, an Arduino Uno, a BTF-LIGHTING WS2812B RGB LED strip from Amazon, and of course the contact microphones. How do I assemble all of this? I do not know hardware assembly so all will be appreciated!

here's how you can setup neopixel LEDs on an Arduino Uno.

the contact microphones probably set up like a regular push button

You can deliver power via barrel jack, USB or VIN Pins, see the doc:

Start from there.

 

AFAIK, Depending on how memory heavy your project is, you might have to use Raspberry Pi or something like STM32F103C8T6 instead

 

The way I see it, you probably will need an additional method incorporated so the light only progress just from a direct hit on the shield.

But yep, not like I ever tried making a project with vibration sensor before, so I might be wrong there.
