Subject Area

Description
This project will look at the capabilities of an Arduino Uno board while also comparing its experimental accuracy in reading guitar frequencies. Steel string guitars are most often tuned a couple of different ways. These methods are either a microphone through audible frequency or a clip on sensor that reads the vibrations of the string through the neck of the guitar. While these methods are easier and more accessible, they allow for a great amount of outside noise and variability in their reading of the string’s output. The Arduino board will achieve the same goal but with less outside disturbance. The board will interact with the incoming electrical signals generated from the changing magnetic field due to the steel strings harmonic motion over a magnet. The manipulation will involve a combination of coding and physical circuitry to convert the raw data into a “tuner” that will tell you how far the string is from the desired frequency.
