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.

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.
