We’ll start with a simple eight-step sequencer, programmed in CircuitPython, and then get a bit more complex with a sixteen-step sequencer that includes effects, beat repeats, and even a live sampler to record your own sounds.
Unlike a MIDI-based sequencer, these two sequencers are self-contained, requiring no external synth or computer. Simply plug in an 1/8″ audio cable and all of the onboard sounds will play through your amplifier or headphones!
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.
