Overview
The goal of this project is to create a device that takes a sound input, specifically from a guitar, and outputs a manipulated sound. The device will utilize a Raspberry Pi to take the input from an instrument and return an edited sound. The coding will most likely be done in C and allows for a unique effects from the standard reverb, fuzz, etc. effects as well as extensive capability to reprogram.

Objectives
- Learn to utilize Raspberry Pi (basics)
- Adapt code from https://www.electrosmash.com/pedal-pi and https://blog.hackster.io/program-your-own-guitar-effects-with-pedal-pi-d77b8c56c0b0 to allow the pedal to run two effects
- Adapt circuitry from the single function pedal on https://www.electrosmash.com/pedal-pi to account for an additional pushbutton to trigger second effect
- Learn how to 3D print a cover and design a cover that allows for usage of both pushbuttons
- Assemble together as a unit and test with guitar and amplifier
Challenges
- Learn to program a Raspberry Pi
- Allowing Raspberry Pi to take input (instrument) and give output (amplifier or microphone)
