The Cartoon Network / Adafruit Industries / Microsoft MakeCode Collaboration

Cartoon Network, Microsoft MakeCode and Adafruit announced in early January 2019 that they are teaming up for a set of new projects and tutorials for kids to learn the basics of coding and stretch their creative muscles.

The hope is that by using Cartoon Network’s fan-favorite characters from shows such as "Steven Universe", “Adventure Time”, "The PowerPuff Girls" and “The Amazing World of Gumball” in projects incorporating Microsoft and Adafruit’s tech tools, they will appeal even to kids who wouldn’t consider themselves coders.

“With software from Microsoft, hardware from Adafruit, and characters that kids love from Cartoon Network, we hope to fuel their creative confidence, self-expression, and curiosity.”

An Introduction to Steven Universe

Steven Quartz Universe is a young half-human, half-gem who is part of the Crystal Gems with Garnet, Amethyst, and Pearl. Together, they help protect humanity against corrupted gems and other strange occurrences. 

The Crystal Gems are a group of revolutionary gems who are trying to destroy the strict caste system of their home planet, ruled by the Great Diamond Authority. The Crystal Gems were formed by Steven's mom, Rose Quartz who gave up her form to help create Steven.

Throughout the series, Steven explores the powers he inherited from his mom and continuing her legacy with guidance from his dad Greg (Mr. Universe), best friend Connie, and the Crystal Gems.

The series also focuses on friendship, acceptance, anxiety, death, grief, and self-identity. It is truly a unique show and touches on more than good vs. bad. Steven Universe touches on real life issues in a way that makes it easy for children to understand and complex enough for adults to appreciate.

MakeCode Projects

Here are some projects Adafruit has already written tutorials for in the Adafruit Learning System with additional tutorials planned.

Steven Universe

Steven Quartz Universe is the series main protagonist, an empathetic and loving half-gem/half human. Steven is the son human Greg Universe and gem Rose Quartz. Greg was a young musician when he met Rose Quartz and gave up his career to spend his life with Rose. Rose was the leader of the Crystal Gems and gave up her physical form to have Steven.

Steven feels the pressure of living up to his mom's legacy, especially since he inherited her crystal and abilities. While developing and mastering his abilities, he progressively accepts his individuality outside of his mom and her accomplishments. With the help of the Crystal Gems, his dad, and best friend Connie, Steven becomes his best self.


Pearl is one of Steven's caretakers and the most strict. Her gemstone is located on her forehead and grants her the ability to create holographic images and store various objects. Pearl's weapon is a spear.

Pearl had a very close, almost obsessive, relationship with Rose Quartz and holds on to her grief. This causes disdain for Greg and an overprotectiveness of Steven. 

Within the Crystal Gems, Pearl is the strategist and usually comes up with the plans to accomplish their missions.


Garnet is the current leader of the Crystal Gems. She is a fusion of two smaller gems, Ruby and Sapphire, and her personality is a combination of the two. Sapphire is a very reserved clairvoyant and Ruby is an impulsive soldier. She is also protective of Steven but allows him room to make his own decisions.

Garnet's gemstones are located on her palms. Her weapon is a pair of heavy gauntlets. Since Sapphire has one eye and Ruby has two eyes, as Garnet she has three eyes in a triangular formation so she wears a visor.


Amethyst is the youngest of the full-gem Crystal Gems. Since she is the youngest, her relationship with Steven is less of a caretaker and more of a friend. She is very childlike and mischievous, often dealing with feelings of inadequacy. 

Amethyst's gemstone is located on her chest and her weapon is a whip.

Rose Quartz

Rose Quartz was the leader of the Crystal Gems and started the revolution against the Great Diamond Authority. According to everyone that knew her, she was loving and cared for all living things. She wanted all gems to be loved and accepted as they are.

Rose's gem was located on her abdomen. Her weapons were a sword and shield.
