Music isn’t just for ears anymore. What ears have done for millions of years, oscilloscopes have done for about a hundred. Grab a thrift store keyboard, an electronic kid’s toy, or any other electronic soundmaker and with a quick hack, turn those tunes into something your eyeballs can enjoy.
This is also a wonderful introduction, to waves, frequency, amplitude, harmonics, and many things under the physics sun. So, take that, you may just get in some learning, too. 🙂

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.

Exactly. This concept is not new. I’ve been doing that since I was a kid. It’s amazing watching waveforms with various sounds and vocals.
