If you’re a guitarist, or understand a guitarist, you most likely understand just exactly how many guitar impacts there are available — however what if you might style your own effects?
[J Rodriguez] has just released his opensource Arduino guitar pedal shield, dubbed the pedalSHIELD. He designed it as a platform to discover about digital signal processing, effects, as well as synthesizers — without needing an thorough understanding of electronics or programming. It enables you to style your own impacts in C/C++, or download from his own library online. Some of the downloadable presets include an octave pedal, reverb pedals, delay pedals, as well as even distortion pedals!
The pedal features three programmable potentiometers, two primary switches, as well as the foot pedal switch. The shield plugs directly into an Arduino Due, as well as you can discover all the schematics here and the parts listing here. It was totally designed in KiCad which is an open source electronics CAD style suite.
Take a listen after the break to hear the pedal in action!
