    Proyectos electrónicos con microcontrolador PIC16F877A
    (2017) Imas González, José Javier; Ruiz Zamarreño, Carlos; Escuela Técnica Superior de Ingenieros Industriales y de Telecomunicación; Telekomunikazio eta Industria Ingeniarien Goi Mailako Eskola Teknikoa
    El presente trabajo fin de grado comprende el desarrollo e implementación de 3 proyectos electrónicos basados en el microcontrolador PIC16F877A. Cada proyecto ha constado de las siguientes etapas: fase de pruebas y programación, diseño del circuito electrónico, diseño y fabricación del circuito impreso (PCB), montaje de los componentes sobre el circuito impreso, puesta en funcionamiento y diseño de una carcasa mediante software 3D. El primer proyecto, en el que la programación cobra mayor importancia, es un relojdespertador basado en la comunicación I2C entre el microcontrolador y el RTC (Real Time Clock) DS3231 y que utiliza una pantalla LCD 2x16. Los dos proyectos restantes poseen un carácter más práctico. El segundo proyecto es un juguete consistente en dos servomotores y un diodo láser controlados de forma autónoma mediante un joystick. El último proyecto es un cubo de LEDs RGB (Red, Green, Blue) 3x3x3 en el que la iluminación de cada uno de los 81 LEDs se controla de forma independiente

    According to recent market studies of the North American company Allied Market Research, the field of photonic sensors is an emerging strategic field for the following years and it is expected to garner $18 billion by 2021. The integration of micro and nanofabrication technologies in the field of sensors has allowed the development of new technological concepts such as lab-on-a-chip which have achieved extraordinary advances in terms of detection and applicability, for example in the field of biosensors. This continuous development has allowed that equipment consisting of many complex devices that occupied a whole room a few years ago, at present it is possible to handle them in the palm of the hand; that formerly long duration processes are carried out in a matter of milliseconds and that a technology previously dedicated solely to military or scientific uses is available to the vast majority of consumers. The adequate combination of micro and nanostructured coatings with optical fiber sensors has permitted us to develop novel sensing technologies, such as the first experimental demonstration of lossy mode resonances (LMRs) for sensing applications, with more than one hundred citations and related publications in high rank journals and top conferences. In fact, fiber optic LMR-based devices have been proven as devices with one of the highest sensitivity for refractometric applications. Refractive index sensitivity is an indirect and simple indicator of how sensitive the device is to chemical and biological species, topic where this proposal is focused. Consequently, the utilization of these devices for chemical and biosensing applications is a clear opportunity that could open novel and interesting research lines and applications as well as simplify current analytical methodologies. As a result, on the basis of our previous experience with LMR based sensors to attain very high sensitivities, the objective of this paper is presenting the route for the development of label-free optical waveguide sensing platform based on LMRs that enable to explore the limits of this technology for bio-chemosensing applications.
