12 pixel NeoPixel ring

Post by savant »

Ran the stock strand test code with NeoPixel ring out of the box, powered from Uno. Only first 8 LEDs light. Using alligator clips, so no heat or solder to affect ring.

If I set number of pixels to less that 8, ring operates as expected. 9 or above, and only 8 light up.

Is this a defective ring, or am I missing something?

Could you post a photo of your setup please? The pad for VCC is fairly close to the data pin on one of the LEDs about halfway around the ring. We've seen rings act half-dead because a wire went a millimeter beyond where it should. It doesn't damage anything, but does block the data signals.

We do not recommend using alligator clips on neopixel rings. Space is tight and it is too easy to short against an adjacent pin or end up with a flaky connection. Better to solder pigtails onto the ring and clip to those.

I understand best practices, but I think I'm pretty clean.

If you still think that's the issue, I'll solder, but it doesn't look that way.

Can I get an opinion here? I'd like to know if I can get this replaced if it's defective.
