This step-by-step guide started as a group project assigned in our Signals & Systems class at the University of Kentucky in Spring of 2017.  The goal of the project was to develop a device that can identify a string of our teacher's guitar based on the sound each string produces and create an easy-to-follow guide to explain the steps.  When researching ideas, we found our favorite design at instructables.com due to our team's strengths in Arduino Uno and circuit building.  The team made a few changes, such as including a SSEG, detailed in "How-To Steps" and "Arduino Code", as well as described the background theory of the project in "Background".

​

Throughout this whole experience, our team kept a journal of our ideas, successes, and failures along the way on Storify. Please follow the link below for an insider's look into the project.
