EGUITAR

Este proyecto busca la creación de un producto con un desarrollo que combine hardware y software para llegar a representar una guitarra eléctrica, pero sustituyendo los principales componentes que la conforman por otros electrónicos, que permitan recrear el funcionamiento de una guitarra eléctrica normal, pasando por sus diferentes etapas de interpretación de las notas musicales que se están tocando, hasta llegar a generar una corriente de salida que represente el sonido. Para ello se investigará en primer lugar como funciona la guitarra eléctrica, así como la historia de la misma para contextualizar el instrumento musical. De esta manera, se podrá comprender mejor su funcionamiento para llevar a cabo un mejor planteamiento al problema propuesto y así implementar un mejor sistema con los componentes y herramientas elegidos. Una vez implementado el principal objetivo del Proyecto, se intentará cumplir con objetivos secundarios como la posibilidad de añadir funcionalidades extra fuera de las que tendría una guitarra eléctrica convencional para mejorar la experiencia del producto por parte de los individuos que le den uso. Entre ellos se puede adelantar el de poder conectar el prototipo, no sólo por cable, si no también añadir conectividad inalámbrica para reproducir el audio generado por el prototipo de nuestro proyecto. Cabe mencionar que en base a los posibles componentes que se elijan tras su estudio, pueden surgir nuevos objetivos e ideas para implementar que puede que se cumplan o no, en función del resultado final del Proyecto, se irán comentando más adelante o se añadirán como posibles líneas futuras o mejoras para otros Proyectos que tomen de base este mismo. Abstract: In the memory of this project carried out that we will see below, are developed all the steps followed for the hardware and software construction of the EGUITAR product, a name given because what is built is an electric guitar, so the name in English GUITAR, and the E added by the changes made to replace the strings with other electronic components, to express the name Electronic-Guitar but abbreviated. It is divided into a total of 14 chapters, in which we will first see how this musical instrument was born and how it has evolved over the decades, as well as how it works and what elements it is made of. Then the current state of the guitar, with innovations that go beyond the standard model of solid body electric guitar, which in the end is what we will do in this project. Next, the general problem is posed, how to carry out the design and construction of this product and what problems are posed by using some development boards or others, as well as the proposed components. Once the main problem and those that this entails have been defined, the proposed solution is given, both at the hardware level, specifying the hardware components used (such as the chosen development board, the ESP32, and the laser sensors, photoresistors and membrane potentiometers, and the reason why they have been chosen) as well as at the software level, explaining the operation of each of the implemented modules, with flow diagrams, and diagrams of the hardware connections to the different GPIOs to explain how the program works internally and how the sound is reproduced. In the same way, it is demonstrated how the respective tests carried out that have been prepared to test the correct operation of the different parts and of the system as a whole work. Once the development of the design and construction has been explained, it is detailed how the project has been planned and the material and human costs involved, carrying out, after that, a study of how to commercialize the product, taking into account different market factors and finished with a proposal for the sale of the implemented product taking into account the income and costs that the manufacture and sale of said product will entail. The impact on society that this product would have, its possibilities, and, in the legal sphere, the measures that can be carried out to patent the product and the brand were also reviewed. To conclude, it is commented on the reasons for choosing this project, and why it has been decided to direct the final degree project and future professional career towards this field of Computer Engineering, as well as the possible future lines of development of this work
