One of the major things I do with Adafruit is write guides, including guides that outline projects or libraries. I want to highlight a few of my favorite guides I've written.
This is easily one of my most favorite guides. I provided guidance on the API, design, and user experience in the Adafruit CircuitPython LED Animation library, while Rose Hooper wrote a majority of the code. The library has become incredibly widely used, and means a lot to many people's experience with LEDs and CircuitPython.
While writing this guide, I built an LED wall, GIFs of which are included in the guide. The wall was behind where I worked, so it was in the background of every video meeting for the duration.
This is the first guide I ever wrote! It'll always have a place in my heart. When I first began with programming and electronics, the first microcontroller I picked up was the Circuit Playground Express. CircuitPython and the CPX were both quite new, and therefore had very little documentation. Once I put together my first project, I immediately wanted to share it so there might be something for other folks also getting started. This is the guide that came of that.
