Jeremy S Cook shares their really cool project using a Digilent Analog Discovery 2 and Raspberry Pi 4 oscilloscope.
Last month I took a trip to South Carolina, where my much more musically talented cousin plays electric guitar, bass, and a number of other instruments. As I now have a portable oscilloscope, I brought it with me for experimentation. What made things even better, however, is that he’d come up with a projector setup for movies, meaning we could hook things up to his screen for musical shenanigans.
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.
