Tyler Worman over at MAKE wrote up this great tutorial on building a three-switch effects looper for the BeagleBone Black.
Many artists will use looping stations to slowly build up an entire song in real-time as they play, recording one track at a time. There are plenty of great examples of this on YouTube. This project will show you how to use a BeagleBone Black, sound card, Python, and Pure Data to build an audio looping station for use with instruments. This looping station will allow you to build a loop, alter tempo, and adjust the loop as it plays. You’ll also lay the groundwork for building very complex synthesizers and effects pedals using the BeagleBone and Pure Data.
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. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
