Diseño, programación y construcción de un dispositivo lector de huellas dactilares, para la seguridad de vehículos con inyección electrónica.

Abstract

This project involves the design of a vehicle ignition system that is achieved through the use of a fingerprint, with the application of automotive knowledge in order to improve automobile security. This system by using a unique biometric factor will allow the reduction of vehicle thefts at a relatively low and accessible cost. The system consists of a fingerprint reader, electronic components and a programming achieved through the Arduino program for the ignition of the vehicle. A quantitative methodology of experimental type was chosen for the present project for which it is directed to the development of the project in search of its operation, the process and its development. This is based on an electronic simulation in addition to the design and programming of the electronic system, together with its implementation and correct operation, having an effective evaluation. Considering also an applied methodology, which is characterized by the development of technical and technological knowledge acquired, such as the set of technologies applied to the automation and control of the vehicle. For the coupling process, the system software was designed and the programming was implemented on the Arduino Nano platform that accepts instructions based on a C++ language, to analyze the signal inputs to be sent to the Arduino Nano platform. Subsequently, the fingerprint reader was adapted to search for the positive signal coming from the battery, which is the contact or start signal by connecting the module which has a 12V power cable on the left side, a signal that closes the circuit and the ground that is connected to the chassis on the right side.
