You can play music with the Trellis M4 by turning it into a great input device for synthesizers. It can send standard MIDI (Musical Instrument Digital Interface) note data over USB MIDI to a software synth on your computer, laptop, (including web browser based synths), or mobile device.
Using the built-in accelerometer (thanks to Analog Devices for the ADXL343), we can also send control change (CC) data, such as mod wheel, and filter cutoff values, and even pitch bend settings just by tilting the Trellis M4 in different directions.
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.
