The Circuit Playground
The Circuit Playground Classic is a small microcontroller board with LEDs, buttons, and sensors built in. Based on the popular Arduino platform, the Circuit Playground Classic enables students to get up and running quickly with physical computing without worrying about many of the traditional barriers to entry. Developed by our friends at Adafruit
, the Circuit Playground is the core tool used in CS Discoveries Unit 6, Physical Computing
Programming with the Circuit Playground
The Circuit Playground is built on the popular Arduino family of microcontrollers. This meas that there are a variety of options for programming the Circuit Playground, including using the standard Arduino IDE. Code.org, however, has developed a special set of commands for App Lab
, our block-to-text app development environment, called the Maker Toolkit. Using App Lab and the Maker Toolkit, students can quickly build apps that communicate with external hardware using the same language and environment they've already become comfortable with.
One of our primary goals in integrating the Circuit Playground into CS Discoveries is to remove the barriers that teachers often encounter attempting to teach physical computing. To that end, we've developed a system that requires only minimal software installation and wide platform compatibility. If using Chromebooks, we've provided a browser extension to install. For all other platforms, we've created a standalone app that allows the programming tools on our website to communicate with the Circuit Playground over USB. Visit the Maker Toolkit setup page for more details on how to get your computers set up.
What’s the difference between App Lab, Circuit Playground, and Maker Toolkit?
The Circuit Playground is an Arduino-based circuit board produced by Adafruit. It has a variety of sensors and ouputs built in.
The Maker Toolkit is an additional set of commands in App Lab that allow you to communicate with and control a Circuit Playground plugged into USB. You can enable the Maker Toolkit in any App Lab project by clicking the settings gear above the toolbox and selecting "Enable Maker Toolkit."
The Maker App is a standalone app that allows the Circuit Playground to communicate with the App Lab and the Maker Toolkit.
Getting Circuit Playgrounds for your Classroom
Code.org has partnered with Adafruit to create a classroom kit
of Circuit Playground boards and accessories necessary for implementing CS Discoveries Unit 6, Physical Computing. The kit contains 15 Circuit Playground boards,
15 Micro USB cables to connect the board to a computer, and a few other accessories. The curriculum is designed for a 2:1 student to board ratio, so a single classroom kit supports a classroom of 30 students.
For teachers in Code.org's 2017-2018 CS Discoveries Professional Learning Program
For teachers participating in the 2017-18 CS Discoveries Professional Learning Program and implementing the full-year version of the course, we're happy to announce that we
will be subsidizing the cost of a single classroom kit for each teacher.
- For teachers at schools with 50% or greater free/reduced price meals, the classroom kit will be 100% subsidized, resulting in no cost to the teacher, including shipping.
- For teachers at schools with less than 50% free/reduced price meals, the classroom kit will be partially subsidized, bringing the cost of the kit to $100 including shipping.
Eligible teachers in our Professional Learning Program should have been sent details on how to receive a coupon code that can be applied directly on the Adafruit website. If you believe that you should have received a discount coupon but did not, please email us at email@example.com
For teachers independently using the CS Discoveries curriculum
While teachers not in the 2017-18 CS Discoveries Professional Learning Program are not eligible for the subsidized cost of the kit, the classroom kit can still be purchased directly on Adafruit's website.
