Robotic Electric Guitar Tuner

Abstract: This report presents the process of building a system thattunes a guitar with the help of an Arduino board, writingalgorithms for processing signals from a microphone andcontrolling the tension of the strings according to the desiredfundamental frequency. The research question for thisproject is how different sample rates affects the accuracy ofthe tuning, different sample rates were examined in orderto find a sample rate that yields the best precision in tuningacross all strings of the guitar.
