Hi all,
I'm a fibre artist in NZ and I'm very new to the whole wearables scene. I was wondering if I could get some advice. I'm weaving a scarf at the moment and I'm hoping that once it is done I'll try and darn some LED sequin lights into it and make it a sparkling scarf. Based on my research so far I have decided to use a GEMMA M0 board and around 15 LED sequins (connected via conductive thread).
So my questions are:
- Is the GEMMA the right board to use for a project like this?
- How do I choose what type of battery I should use? The smaller the better if possible.
Thank you for your help

Re: Woven sparkle scarf
A Gemma has only 3 GPIO pins and would not be able to drive 15 sequins. Each pin can drive at most 2 or 3 sequins.
You could use a processor with more pins such as a Flora or a CircuitPlayground. Or you could use Neopixels. The Neopixels are a bit bulkier than the sequins, but they are simpler to connect and you can control any number of them with just one GPIO pin.

LiPo batteries are a good choice for your project. They come in a variety of sizes. As you might expect, the power capacity is roughly proportional to the size. So the best choice will depend a bit on how much run-time you expect from a charge.

Re: Woven sparkle scarf
Thanks so much! I think ill go down the neopixel route then.

I should have posted this link for you. It covers the basics of working with Neopixels: https://learn.adafruit.com/adafruit-neopixel-uberguide
