It’s been quite a journey for home audio, as it has been at the forefront of technology for an unbelievable 162 years. We may think it all started with Edison’s cylinder recorder/player, but in fact Edouard-Leon Scott de Martinville beat him by 20 years, inventing the Phonautograph in 1857, transcribing sound waves onto smoke-blackened paper or glass.
From the Gramophone in 1888 to the first record player in 1920, the first reel-to-reel tape machine in 1947, the first in-car radio (courtesy of Blaupunkt) in 1950, through the beginning of digital audio playback technology with the CD in 1982, if there’s been a new technological development, home audio (and pro audio for that matter) has been right there with it.
From the first headphones made by John Koss in 1958, to Logitec’s Bluetooth speakers in 2013, the immersive sound of Apple’s HomePod, to IKEA’s own upcoming Bluetooth speakers in 2019, there’s been a search for better quality reproduction and portability (with varying results, as we all know).
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
