Electronics noob so be gentle.
So I was following the Kaleidoscope Eyes tutorial to run 2 NeoPixel Rings off a Trinket but I cannot seem to get the LEDs to work. I finally was able to get the code to upload without error (what a pain) but the pixels won't light up. Power is running through them fine according to the volt meter. I get 1 led to light up touching it to a 9v.
Is it not getting enough power ?
2 - 24 LED NeoPixel Rings (part 1586)
1- 5v Trinket (part 1501)
1- Adafruit Micro Lipo - USB LiIon/LiPoly charger [Part 1304]
I have them wired as the diagram shows except my pixels are the 24 and battery is 3.7v 500mah. Everything seems to have power just no action.

If you post photos showing your soldering and connections we can take a look.I get 1 led to light up touching it to a 9v.
But unfortunately, your ring is almost certainly dead. Neopixels can be damaged by as little as 6v. Connecting 9v to it would destroy it pretty quickly.

Yea I didn't think that was a good idea on the 9v.
Here is the wiring, kinda messy. I took out the switch I had rigged up.
The green trinket light stays on the and red blinks.

Re: NeoPixel Rings not working on Trinket 5v
Neopixel rings are tricky to solder since the solder pads are tiny and very close to the pixels. I don't see any solder bridges, but you do have some un-insulated wire that could easily short out against an adjacent pixel pin.
Short circuits on these rings typically result in all downstream pixels not working. But since you didn't have any lighting up, we'll give you the benefit of the doubt on that first ring. If you contact [email protected] with a link to this thread we can replace that for you.
