Abstract

This paper presents the design concept, implementation and verification process of the Electronic Assisting Violin Tuner (EAVT). The analysis of the violin sound to extract the frequency information was done using a Goertzel filter which was optimised and embedded to a microcontroller. The resulting frequency information is used to control actuators to tune the violin. Safety issues have also been considered and appropriate actions have been taken to reduce the risk of accidental string breakages which could result in injuring the violinist. The goal of this project was to develop a device to assist in tuning every string of the violin. This project was undertaken with intentions that it could be further developed to increase the stability and robustness to the level that the prototype is fit for the market. It is therefore expected that there is still many areas of this project to improvement upon.
