Experiencing back to school schedule jitters? Make a class scheduler with Circuit Playground!

Have you already made this project or a remix of this project? Let us know! We want to see all the creative ways you’ve been using Circuit Playground this month. Share your projects on social media or on our #AdafruitExtraCredit channel on Discord for the communityto see with #AdafruitExtraCredit #CircuitPlayground and submit them at Adafruit.com/ExtraCredit!


Circuit Playground Class Scheduler – keep track of tricky schedules, Monday through Friday!

We can program the schedule into the Circuit Playground and then use it as a sort of cheat sheet to quickly check which class is happening at which period on a given day.

Instead of having the schedule written out as a bunch of text on a paper schedule or a digital display, the ten colored NeoPixels on the Circuit Playground can convey a lot of information very efficiently. We use the five NeoPixel LEDs on the right half of the board to indicate the day of the week, and the five on the left to indicate class periods one through five. The class period NeoPixels are color coded to the same color folder he uses for that class, so, green = science, for example.

We also built a pretty cool mounting panel with informational call-outs for the Circuit Playground that can be attached to his backpack with magnets, but this is optional. You can skip it entirely, or come up with your own solution.

Follow along as this guide will show you how to program and build your own Circuit Playground Class Scheduler!
