The search for more reliable security systems and information management of these systems is leading to a growing progress in new technologies investments that allow the implementation of equipment with a high level of reliability, but also have an agile and practical operation. This led people to turn increasingly looking for home automation systems, enterprise and industry for the automation and integration of their systems. The identification by radio frequency is very widespread today for ensuring both agility in handling records data, the reliability of their identification systems, which are increasingly advanced and less susceptible to fraud. Attached to this technology, the use of the database is always very important for the storage of information collected, the area where the MySQL platform is widely used. Using the open source Arduino platform for programming and manipulation of RFID module and LabVIEW software for the union of all these technologies and to develop a user-friendly interface, you can create a highly reliable access control and agility places a high turnover of people. This project aims to prove the advantages of using all these technologies working together, thus improving a flawed system effectively safety, cheaper and quicker

This paper presents a Project of an automatic feeder for pets using an Arduino Uno as the control center. Through studies on this driver was possible to create a device with an interface capable to receiving user input and then use it to activate the feeder in the defined hours. For mounting equipment were used steps motors, sensors, keyboard and display, which work together to instrument operation. The project goal was reached and the prototype developed indicating that the Arduino can be used for various applications that can simplify daily tasks

The education designed and planned in a clear and objective manner is of paramount importance for universities to prepare competent professionals for the labor market, and above all can serve the population with an efficient work. Specifically, in relation to engineering, conducting classes in the laboratories it is very important for the application of theory and development of the practical part of the student. The planning and preparation of laboratories, as well as laboratory equipment and activities should be developed in a succinct and clear way, showing to students how to apply in practice what has been learned in theory and often shows them why and where it can be used when they become engineers. This work uses the MATLAB together with the System Identification Toolbox and Arduino for the identification of linear systems in Linear Control Lab. MATLAB is a widely used program in the engineering area for numerical computation, signal processing, graphing, system identification, among other functions. Thus the introduction to MATLAB and consequently the identification of systems using the System Identification Toolbox becomes relevant in the formation of students to thereafter when necessary to identify a system the base and the concept has been seen. For this procedure the open source platform Arduino was used as a data acquisition board being the same also introduced to the student, offering them a range of software and hardware for learning, giving you every day more luggage to their training

No presente estudo, 100 fêmeas bovinas foram divididas em cinco grupos de 20 animais cada. Os grupos experimentais receberam quatro diferentes vacinas comerciais (B, C, D e E), e um grupo permaneceu como controle. Amostras foram colhidas no dia da aplicação da primeira dose e nos dias 3, 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84, 91, 120, 150 e 180 pós-vacinação (PV). A triagem dos animais foi feita pela análise sorológica com 6 antígenos de leptospiras, escolhendo-se os animais não reagentes. Os títulos de anticorpos foram monitorados pela soroaglutinação microscópica (SAM) com os sorovares Canicola, Grippotyphosa, Hardjo, Icterohaemorrhagiae, Pomona e Wolffi. Todas as vacinas induziram, aos 3 dias PV, títulos de anticorpos aglutinantes para os sorovares Hardjo e Wolffi, que persistiram até o 150º dia PV. Os sorovares Hardjo e Wolffi induziram os maiores títulos de anticorpos aglutinantes. A vacina D, apesar de não possuir o sorovar Wolffi em sua composição foi capaz de induzir anticorpos aglutinantes contra este sorovar. Somente foram detectados anticorpos contra o sorovar Canicola nos animais vacinados com a bacterina D. A vacina que induziu os maiores títulos médios de anticorpos, considerando todos os sorovares testados foi a D.

Mediante a utilização da prova de soroaglutinação microscópica (SAM), foi pesquisada a indução de anticorpos contra leptospira em bovinos vacinados com uma bacterina polivalente comercial. Procurou-se avaliar a resposta sorológica homóloga frente a dois esquemas de vacinação. Os animais utilizados foram fêmeas adultas em produção leiteira oriundas de seis propriedades da região noroeste do Estado de São Paulo. Vinte animais de cada propriedade foram escolhidos após três exames sorológicos com 24 sorovares de leptospiras com intervalo de 20 dias, através de triagem sorológica com 24 antígenos de leptospiras. Os grupos foram constituídos de animais não reagentes (I, II e III) e animais reagentes (IV, V e VI). Posteriormente os animais foram subdivididos em grupos controle (I e IV), os que receberam somente uma dose de vacina (II e V) e que receberam duas uma doses de vacina com e dose de reforço após 30 dias (III e VI). Os animais foram monitorados por meio da SAM nos dias 0, 15, 30, 45 e 60 após a primeira aplicação da vacina. Os resultados obtidos revelaram que não houve diferença significativa (p>0,05) entre os animais vacinados e não vacinados. Não houve diferença significativa (p>0,05) nas respostas de títulos vacinais com relação ao perfil sorológico apresentados pelos animais. A vacinação com reforço apresentou melhor desempenho e a indução produção de aglutininas somente ocorreu contra os sorovares hardjo, wolffi, icterohaemorrhagiae e pomona. Há a necessidade de maiores estudos sobre o poder imunogênico da vacina utilizada no experimento.

This paper presents a study on the development of a manufacturing system of printed circuit boards through copper milling. An advantage of this system is the replacement of chemical processes by physical process presenting a sustainable solution. The paper uses programs that will generate G-code needed to establish the coordinates where the milling forms the tracks. After obtaining the code, it will be transformed into steps that will be sent through the serial port to the microcontroller and the serial communication control will be in software. After obtaining information the microcontroller will execute the movement of the stepper motors through their drivers, H-bridge, the microcontroller also drives the spindle motor responsible for rotating the grinding tool, using a driver with a optocoupler and TRIAC

The present work refers to the design, conception and development of a quadcopter based on PID controllers, a widespread microcontroller on the market was being implemented, the Arduino. Also made use of LabVIEW programming tool from National Instruments company for the quadcopter control and telemetry. For the control, LabVIEW software acquired the joystick commands, making the necessary adjustments to the perfect interpretation by microcontroller on the quadcopter and adjusts the parameters of PID controllers. For telemetry, data relating to quadcopter behavior are received, interpreted and presented in an intuitive user interface. In the first part of this graduate work presents the theoretical background on the subject, with a brief history about the quadcopters, followed by the main projects in the academic and commercial matters. Also are presented the theories of communications used in the design and PID control. Then an overview of the dynamic and mathematical model is demonstrated. Having done this, the physical and computer components required to complete the project are showed and the results are achieved consequently. Finally, a conclusion is made taking into account the results obtained. In this work will be presented the PID control of quadcopter translational movements only to roll and pitch movements
