The build is a straightforward one, thanks to the prevalence of modern maker solutions to electronic problems. Hooking up to the guitar is a solved problem, with an Adafruit Nunchucky breakout board allowing the Guitar Hero controller to be connected via jumper wires to the Raspberry Pi’s IO pins.
Communication is via I2C, and is easy to work with in Pure Data, running on the Pi. [Analog Sketchbook] created a patch that runs a synthesizer, controlled by the buttons and controls on the guitar itself. With this setup, you could create any number of different routines to allow the guitar to be played differently. We’d love to see a chiptune-esque arpeggio patch, or something that plays fat FM synth tones a la the Genesis, but that’s just our opinion. The sky really is the limit here, with plenty of grunt on the Pi for various forms of synthesis.

Adafruit has had paid day off for voting for our team for years, if you need help getting that going for your organization, let us know – we can share how and why we did this as well as the good results. Here are some resources for voting by mail, voting in person, and some NY resources for our NY based teams as well. If there are additional resources to add, please let us know – adafruit.com/vote
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.
