A new guide in the Adafruit Learning System: Circuit Playground-O-Phonor

With a simple musical recorder, you can both make lights corresponding to the notes played or display the note being played.

Remember the holophonor from Futurama? It was (will be?) a musical instrument that would project holograms depending on the mood of the note played.

Being a futuristic instrument, the inner workings of the holophonor are unknown. However, the basic idea of being able to detect the frequency of musical notes is something we can possibly emulate. And that is what we’ll explore in this guide using a fairly simple technique.

We’ll also use the frequency detection to drive NeoPixels (our version of the holophonor) and also show how a TFT Gizmo can be used to display the note information.

As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email circuitpython2022@adafruit.com to let us know about your post so we can blog it up here.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
