NEW GUIDE: John Park’s Spinning Disc Step Sequencer @adafruit @johnedgarpark #adafruit #synthdiy
The Spinning Disc Step Sequencer Learn Guide is live! Play fresh drum patterns with this 16-step disc sequencer, made with CircuitPython on Feather M4 Express and Crickit! It uses reflection sensors to read the steps marked on the paper wheel — four tracks of different sound samples can be triggered. The outer clock track keeps everything synchronized.
You’ll use a continuous rotation servo to spin the disc, driven by the Crickit FeatherWing, plus the capacitive touch pads provide tempo controls to increase or decrease the BPM (beats per minute) of your player. CircuitPython code running on the Feather M4 handles all of the coordination of the elements, and audio mixer playback duties as well.
You can even create and edit your own drum step patterns with a blank paper template and a black chalk marker!
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.
