# Machine Learning with Marshmallows and Tiny Sorter ## Overview ![](https://cdn-learn.adafruit.com/assets/assets/000/087/663/medium800thumb/projects_main-front.jpg?1580158410) Machine learning is only about as complicated as cereal and marshmallows in this guide. [This project from Google](https://experiments.withgoogle.com/tiny-sorter/view) uses a laptop's built-in camera to identify various cereal and marshmallows. The computer then sorts them based on a model you train. A [Circuit Playground Express](https://www.adafruit.com/product/3333) communicates with the computer to decide when to sort which marshmallow/cereal via a micro servo. ## Parts ### Circuit Playground Express [Circuit Playground Express](https://www.adafruit.com/product/3333) **Circuit Playground Express** is the next step towards a perfect introduction to electronics and programming.
