pedalSHIELD is an Open-Hardware / Open-Source Arduino guitar pedal shield. It is designed as a platform to learn about digital signal processing, guitar effects, and synthesizers — without needing an in-depth knowledge of electronics or programming.
It allows you to design your own effects in C/C++, or download them from the online library.
Some of the downloadable presets include an octave, reverb, delay and even distortion pedals!
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.
