Today, there is an innumerable amount of electronic devices and computer systems that are oriented as platforms for the management of information through the network; manipulating data and at the same time, performing tasks using low voltage electronic signals. They can activate, deactivate or control a device or a system using sensors. In this context, the Raspberry Pi platform has an interface composed of a set of pins (GPIO) through which voltage signals can be accessed, and can interact with other electrical and electronic systems for data acquisition and control. This article aims to facilitate access to the Raspberry Pi platform from its installation, configuration, to its programming of the ports through examples and instructions, considering the platform as a computer system. The interest of the authors is to provide the reader with the tools, so that the programming of specific applications is the new challenge.
Nowadays, the development of software radio based systems has allowed the transmission of data at high speeds and frequencies in the order of Gigahertz (Jovanovic, 2018). For this, the digital system is characterized by using digital modulation techniques in software through transmission symbols in the DigitalEnd stage, applying digital-analog (DAC) and analogdigital (ADC) converters to vary the sampling frequency and transmit the data in the Front End, (Chien, 2001). This work presents a digital educational platform to simulate the characteristics of a Software Radio system and not a web platform. The present investigation is focused on the characterization of signals modulated by Octave considering in the first instance the quadrature modulation QPSK, where the transmission of the modulated signal is carried out by means of the Arduino board in a digital port, with a digital-analog approach (DAC) using PWM modulation a RC filter and an amplifier circuit, which synthesize the signal considering the limitations of the Arduino board. The proposed design presents an electronic platform that will allow the understanding of software-based radio systems.
This article presents an electronic prototype for vehicle tracking based on GPS (Global Positioning System) location as a proposed solution to the problem of vehicle theft that affects the Oaxaca de Juarez municipality and its surrounding municipalities, according to statistics from the Office of the Prosecutor Specialized in High Impact Crimes, vehicle thefts have increased rapidly in recent years. The "V" diagram was used to make the prototype, which proposes a solution within reach of the owners of vehicles, since similar products require the device and the payment of a membership to follow up in real time. The prototype consists of an Arduino board, a GPS module, a communication module for sending SMS (Short Message Service) messages, an accelerometer to detect vehicle movements and other components that are required for the operation of the complete circuit. The program has been developed in C language for Arduino and a free application of GoogleMaps is being used to send the location of the vehicle when detecting any vehicle movement
