You can turn an old Guitar Hero accessory into a USB MIDI controller for your synthesizer! Wii accessories use I2C to send all of their data, so we’ll couple the Guitar Hero controller with a STEMMA QT Nunchuck Breakout and a QT Py to read all fret buttons, whammy bar, strum bar, and joystick data.
You’ll be able to send MIDI notes, chords, octave changes, whammy bar pitch bends, and joystick CC messages to any software synth, or USB MIDI host-capable synthesizer.
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.
