I am trying to figure out if I can use existing extenstions in a custom makecode tutorial. Specifically the Neopixel extension with Microbit.
Is there a way to use extensions in the tutorials space
I have built my custom tutorial with
[https://makecode.com/writing-docs/tutorials](https://makecode.com/writing-docs/tutorials)
The below does not work as the neopixel extension is not enabled in the tutorial.
`let strip2 = neopixel.create(DigitalPin.P0, 24, NeoPixelMode.RGB)`

For builtin extensions: at the bottom of [this file](https://raw.githubusercontent.com/microsoft/pxt-arcade/master/docs/tutorials/simple-extensions.md), you can see the packages snippet that indicates the extension the tutorial needs to load. I would expect you just need neopixel there instead of corgio, but I’d have to check. (If you need multiple extensions, just add another line)
For extensions on github: This tutorial I wrote uses an extension that handles almost all of the game logic, so there are just a few blocks the play can customize it with. To get an extension in your project, you’ll want to add a snippet with syntax like the bottom [here](https://raw.githubusercontent.com/microsoft/pxt-arcade/master/docs/tutorials/football.md).
Ill see about updating the docs later to be clear on gow to do this~

Cheers @jwunderl,
I tried the following and unfortunately came up with no extension being loaded.
`package pxt-neopixel `
And
`package neopixel `
And
`package pxt-neopixel=github:microsoft/pxt-neopixel#v0.6.12 `

Ahh, forgot that neopixel is in a separate repo; the last one should be working I believe? E.g. example below shows up as [https://makecode.microbit.org/beta#tutorial:22058-41215-69115-76860](https://makecode.microbit.org/beta#tutorial:22058-41215-69115-76860)

Cheers for that, I must have had a typo in my test.
That solved the issue I was having 🙂
