'Best' means more than 'newest, biggest, and fastest'. Today there are some great microcontroller boards to realize your ideas. This guide will help you look at choices available and help you decide on the right microcontroller for your implementation.

Getting Started

Adafruit Playground is a wonderful and safe place to share your interests with Adafruit's vibrant community of makers and doers. Have a cool project you are working on? Have a bit of code that you think others will find useful? Want to show off your electronics workbench? You have come to the right place.

The goal of Adafruit Playground is to make it as simple as possible to share your work. On the Adafruit Playground users can create Notes. A note is a single-page space where you can document your project using Adafruit's easy-to-use editor. Notes are like Guides on the Adafruit Learning System but are simpler and more concise. Guides are high-fidelity content curated and maintained by Adafuit. Notes are whatever you want them to be. Share a single picture of a project, or journal a complex project as you work on it. Have fun and be kind.
