Flora Sewable Neopixels and BBC Microbit

Post by StephCote »

Hi,

I'm a very beginner with coding, so I use the BBC Microbit system and block's coding. I'm wondering if I can use the little Flora sewable noepixels with the Microbit as the board (not the Flora board). I bought Flora Neopixels - Flora RGB Smart NeoPixel version 2 - Sheet of 20 (Product ID: 1559) and I try to connect them to the Microbit, and only the first little Flora is doing what I'd code. The others are doing just flashing red, that's it. Is it normal?

Thank you for helping me.

Please post some photos showing all of your soldering and connections.
Also please post the code you are using.

Hi,

Here is the link to my code on Makecode: https://makecode.microbit.org/_140McuUPy3aE. Of course, I adjust the number of Neopixels that I plugged together.

Here are the link to two videos showing my connections:

- 2 Floras: https://drive.google.com/file/d/1VAh1wG ... sp=sharing

The code and Microbit work very well with a strip of Neopixels: https://drive.google.com/file/d/1vqWMqK ... sp=sharing

And I tried to sew the Flora with the Thin conductive Thread sold with the Flora and it's doesn't work at all...


That's why I'm wondering if the Sewables Flora Neopixels can work with the BBC Microbit as a board, instead of the Flora Board.

Thank you for your help.

The neopixels need 3 connections each: Ground, 3v and the signal pin. Your second Neopixel has only 2 connections. Looks like just ground and signal. You need a 3v connection to properly power it.
