Hi! I want to build a triggered LED for my drums, and I found the perfect guide here on Adafruit.
The problem that its dated, and I don’t understand if I can still use Gemma for this, and if it wil work with my mac (macbook pro 2019)
One of the featured prosuct for this project is the “Metro M4”, and I dont understand if i need this or the gemma, and if i need the metro, how do I connect the wires?
Btw, I have no idea about how all this works, Im a musician who is looking for a cheap alternative to the market of Triggere LED.

Re: Drum triggered LED help
I would avoid the Gemma V2. The code doesn't look to be Gemma V2 specific so you should be able to use pretty much any controller board. The Gemma M0 https://www.adafruit.com/product/3501 would be the most direct replacement. A Trinket M0 https://www.adafruit.com/product/3500 or QTPY https://www.adafruit.com/product/4600 should work as well.
Note that the Gemma M0 has a battery connector; there'd be a bit of work to add one to either of the other boards.

So if il take the Gemma, il spare the work of soldering the battery?
And one last question, how do I know where to connect the wires of this project if the scheme in the article is for Gemma v2?

Re: Drum triggered LED help
Yes, the Gemma M0 has an onboard battery connector. Just get a LiPo and plug it in. Be sure to get a LiPo with the right polarity wiring. Getting one from Adafruit is the safest option.
The connections should be the same. The Gemma M0 is meant to be a more-or-less drop in replacement for the V2.

I have another question if it ok :)
In the featured products of the project that I want to do, which is the LED drum triggers, there is a "Adafruit Metro M4 feat. Microchip ATSAMD51", which I don't see in the guide, or in the video, why Is that product on the featured product list?

Re: Drum triggered LED help
No idea. It's quite a different board than the Metro. And *not* usually battery powered. If going beyond the Metro type board, a Feather would be the way I go (they have onboard battery support). But the Gemma M0 is perfectly adequate and is easy to connect to. I do advise soldering if possibly, though, just to get solid, reliable connections.
