Purpose. The paper describes development of a device (placed on the Arduino platform) for recording wind waves. It is intended for the wave gauge of Marine Hydrophysical Institute, RAS, which is installed and applied at the oceanographic platform in Katsiveli. The device is designed to record and store the wave gauge data in an off-line mode. At that, it is protected from power surges and environmental effects (dust, moisture, temperature drops). Methods and Results. Two versions of the Arduino-placed recording device are represented: for the single- and six-string wave gauges. Their hardware and software are described; block diagram of the applied software algorithms and electrical connection schemes are given. Particular attention is paid to stable functioning of the devices, namely continuity of the data reading, recording and storing, as well as synchronization of the obtained measurement results with the time of record. The example of the sea level elevations recorded in course of a year is cited. Conclusions. Development, construction and testing of the Arduino-placed device for recording wind waves are described in the paper. Since 2015, the off-line operation of the device has shown high efficiency, reliability and stability; at that, the risks of losing the measurement results are minimal.

The work was divided into two main parts. The first one dealt with the analysis of the problem of influencing the performance of photovoltaic panels by active cooling. Based on the results of the analysis, an optimal system for active cooling was designed with respect to the performance enhancement but also to the damage elimination possibilities. The parameters for the implementation of the system were specified depending on the analysis performed. This analysis provided answers to the choice of the appropriate technology and to the technical design of the whole system. The second part of the work presented the actual technical solution. In the form of its design, construction, programming and testing of the resulting system.

The use of robotics systems in education also known as "Educational robotics", "Robotics in education" is gaining popularity as a trend. This is evidenced by the increase in the number of publications on this topic in scientific journals and conducting an experiment at the national level on "Methodological system of teaching the basics of technology and robotics as part of STEM-education" by the Ministry of Education and Science of Ukraine. The rapid development of the robotics industry necessitates training of appropriately qualified specialists. However, school remains a traditional place to master basic competencies needed to determine the professional orientation of a person, and familiarity with robotics increases the chances of students choosing this area of activity in the future. Teachers mainly choose the most common technical tools for teaching robotics, which has both advantages and disadvantages. It is important to develop a classification of educational technical solutions that already exist and are used in the process of teaching the basics of robotics at school. The paper analyzes sets of components used in teaching the basics of robotics for school-aged children, explores 84 different technical solutions that can be used in the process of learning robotics, and identifies common and distinctive features. As a result of the research a classification of robotic platforms and ready-made technical solutions was offered for use by teachers in the process of teaching students the basics of robotics. In the perspective of further research, it is planned to develop methodological recommendations for the selection of content and means of teaching the basics of robotics to secondary school pupils., Використання роботизованих систем у навчанні, широко відоме, на теперішній час, як “Освітня робототехніка”, “Educational robotics”, “Robotics in education”, все більше набирає обертів як тренд. Про це свідчить як збільшення кількості публікацій на цю тему в наукових виданнях, так і проведення експерименту всеукраїнського рівня за темою «Методична система навчання основам технології та робототехніки як складової STEM-освіти» за підтримки Міністерством освіти й науки України. Стрімкий розвиток галузі робототехніки спричиняє потребу в підготовці відповідних кваліфікованих фахівців. Однак, школа залишається традиційним місцем опанування основних компетентностей, необхідних для визначення професійної орієнтації людини, а ознайомлення з робототехнікою підвищує шанси на вибір учнями цього напряму діяльності в майбутньому. Найчастіше вчителі обирають найбільш розповсюджені технічні інструменти для навчання робототехніки. Такий підхід хоч і має свої переваги (використання готової навчальної програми та інших ресурсів навчання) , але має і недоліки. Тому важливим є розробка класифікації технічних рішень, що вже існують на ринку та використовуються у процесі навчання основ робототехніки в школі. У статті проаналізовано конструктори та набори компонентів, що застосовуються в процесі навчання основ робототехніки для дітей шкільного віку, досліджено 84 різних технічних рішень, що можуть бути використані для навчання робототехніки, та розглянуто їх спільні й відмінні риси. У результаті дослідження запропоновано класифікацію робототехнічних платформ та готових технічних рішень для використання вчителем у процесі навчання учнів основ робототехніки. В перспективах подальших досліджень планується розробка методичних рекомендацій для добору змісту і засобів навчання основ робототехніки в закладах середньої освіти.&nbsp

Nowadays, the rapid developments in science and technology have an impact on education as well as on all gear units. The integration of technology into the education process offers effective opportunities, particularly in the fields of STEM (Science, Technology, Engineering and Mathematics). In this context, Arduino platform has started to be used as a low cost, easy to use microcontroller in physics teaching. In this study, an Arduino-based physics experiment that can be used in physics laboratories was designed. We have used Arduino platform to study temperature dependence of electrical resistance and to define the temperature coefficient for a conductor. Experimental data were collected using the Arduino ohmmeter and a temperature sensor. The resistance-temperature curve obtained is in the expected character and the temperature coefficient is in the expected value. With this experiment, the student can easily observe the temperature change of the conductor's resistance and calculate the temperature coefficient of the resistance. The Arduino-based apparatus is presented as a simple and low cost alternative to physics laboratories.

Dissertação de mestrado em Ciências Educação (área de especialização em Tecnologia Educativa), A Dissertação do Mestrado em Ciências da Educação – Especialização em Tecnologia Educativa, que apresentamos teve como objetivo compreender as perceções dos professores e dos alunos sobre a utilização da plataforma Arduíno na construção dos projetos interdisciplinares nos cursos profissionais. Os cursos profissionais têm a duração de três anos e pressupõem no seu currículo a realização de projetos de natureza interdisciplinar, perspetivados de molde a integrar os saberes e competências adquiridas ao longo do curso. Neste estudo focamo-nos nos projetos referentes à Prova de Aptidão Profissional (PAP) que os alunos realizaram no último ano do curso Técnico de Gestão de Equipamentos Informáticos. Sendo este um curso prático, laboratorial, os alunos têm que manusear equipamentos informáticos e eletrónicos para construir os seus projetos. Tendo em conta estes requisitos passou-se a utilizar na construção dos projetos a plataforma Arduíno, que é open source e para a sua programação os nossos alunos usaram o software Arduíno IDE. A opção metodológica que seguimos foi de natureza qualitativa e interpretativa e com um design de estudo de caso. Para cumprirmos com este estudo, realizamos uma revisão de literatura que foi dividida em duas partes. Na primeira parte fizemos um enquadramento do Curso e da plataforma Arduíno. Na segunda parte, efetuamos uma revisão sistemática de literatura, da qual resultou o quadro teórico que utilizámos para analisar os dois focus group, com professores e alunos, com o objetivo de responder à nossa questão de investigação. Dos resultados obtidos neste estudo, da parte dos professores existe a perceção de que a utilização da plataforma Arduíno na construção dos projetos refletiu nos alunos maior motivação e interesse pelas atividades práticas; promoveu autonomia, resiliência e desenvolvimento de competências transversais na realização dos projetos. Relativamente aos alunos, as grandes vantagens desta plataforma Arduíno são o facto de ser simples de trabalhar, de fácil acesso de compra, ter um custo acessível, ter uma linguagem de programação open-source e existir muito material documentado para consulta em vários sites da Internet., The Master's Dissertation in Educational Sciences - specialization in Educational Technology, which we presented aimed to understand the perceptions of teachers and students about the use of the Arduino platform in the construction of interdisciplinary projects in vocational education and training (VET) courses. VET courses have a duration of three years and assume in their curriculum the realization of projects of an interdisciplinary nature, aimed at integrating the knowledge and skills acquired during the course. In this study, we focus on projects related to the Professional Aptitude Test (PAP) that the students carried out in the last year of the Computer Equipment Management Technical Course. This being a more practical course, students have to handle computer and electronic equipment to build their projects. Taking these requirements into account, the Arduino platform, which is open-source was used in the construction of the projects and for its programming our students used the Arduino IDE software. The methodological option we followed was of a qualitative and interpretative nature and with a case study design. To carry out this study, we carried out a literature review that was divided into two parts. In the first part, we did a brief overview of the Course and the Arduino platform. In the second part, we performed a systematic, from which resulted in the theoretical framework that we used to analyze the two focus groups, with teachers and students, to answer our research question. From the results obtained in this study, teachers perceive that the use of the Arduino platform in the construction of projects is reflected in the student’s higher motivation and interest in practical activities; promotes autonomy, resilience and development of transversal skills in carrying out projects. Regarding students' perceptions, the significant advantages of the Arduíno platform are the fact that it is simple to work with, easy to buy, affordable, has an open-source coding language and there is a lot of documented material on Internet sites for consultation.

The paper describes a system for automatic control of microclimatic factors based on the Arduino platform, whose work and functionalities are shown on the model of the system itself. The Arduino Uno is a control unit of the system that, according to the measurements read from the sensors of temperature (DHT22), humidity and soil (YL69) and light intensity (photoresistor/LDR), controls the ventilation, irrigation, lighting and indication of the need for heating. To monitor the measured values from the sensor and set the optimal limits required for higher and better plant yield, a Nextion touch screen was used, with which the user can easily change the optimal limits value according to the needs of the plant culture. The paper explains the technologies used and the necessary components for system design. The connection of each component with the Arduino platform is explained in detail, accompanied by diagrams and the necessary program code for proper operation. Also, the purpose of each sensor and executive elements in terms of the automation system is explained. Finally, the created model of the system is shown with all the associated parts connected into one ensemble and placed in the appropriate places of the system model. Also, testing of the system itself was done to show the purpose and mode of operation to create optimal microclimatic conditions in the protected area. The whole system is designed to be modular, so that it can be upgraded as needed. The very cost- effectiveness of such a system is assessed by the greenhouse user himself, ie, in this case it is valid: if the payback period is less than the specified project life, the investment is acceptable. the shorter the payback period, the more justified the investment.

Autonominiai robotai pritaikomi įvairiausiose srityse – pradedant nuo namų ūkio, baigiant karo pramone. Jau netolimoje ateityje, autonominiai robotai neišvengiamai taps vis išmanesni ir atsiras beveik kiekvieno žmogaus namuose. Todėl verta susirūpinti saugaus komunikavimo metodo naudojimu, kuris padėtų išvengti savanaudiškų pašalinių asmenų ir kenksmingų atakų, kurių metu įmanomas slaptų, asmeninių duomenų nutekėjimas. Tačiau kuriant saugų komunikavimo metodą autonominiam robotui būtina atsižvelgti į jo ribotus išteklius – tiek elektros energijos sunaudojimą, tiek ne itin galingus skaičiavimo operacijų pajėgumus. Šiam tikslui pasiekti galima naudoti supaprastintus ir sudėtingesnius komunikacijų protokolus, tačiau būtina įdiegti papildomą saugą. Dėl šios priežasties, baigiamojo darbo tikslas yra patobulinti esamus autonominio roboto komunikacijos metodus saugos srityje, taip pasiūlant veiksmingą komunikacijos apsaugos metodą. Sukurtas metodas privalo tenkinti roboto ribotų išteklių keliamus reikalavimus: būti pakankamai saugus ir greitas, tačiau nenaudoti per daug skaičiavimo išteklių bei elektros energijos. Literatūros analizėje apžvelgiamos ir ištiriamos esamos robotų saugos problemos ir pažeidžiamumai, palyginami naudojami komunikacijos metodai. Baigiamojo darbo metodo prototipe realizuojamas saugus komunikavimas naudojant dviejų rūšių protokolus – HTTP ir MQTT. Galutiniai baigiamojo darbo rezultatai pateikiami eksperimentiniame tyrime, kur palyginamos protokolų saugos lygmenų modifikacijos, skaičiavimo išteklių naudojimas, greitaveika, atsirandantis papildomas duomenų srautas ir suvartojamas elektros energijos kiekis., Autonomous robots are used in a wide range of areas, ranging from households to military industry. Soon autonomous robots will inevitably become more intelligent and will be used in almost every person's home. Therefore, it is time to think about using secure communication method that would help to avoid selfish strangers and malicious attacks that could allow the leak of sensitive personal data. However, when developing a secure communication method for an autonomous robot, it is necessary to consider its limited resources - both power consumption and low power computing capabilities. Both simplified and more sophisticated communication protocols can be used to achieve this, but additional security needs to be implemented. For this reason, the aim of the final thesis is to improve the existing methods of autonomous robotic communication in the field of safety, thus offering an effective method of communication protection. The developed method must meet the requirements of the robot’s limited resources: to be safe and fast enough, but not to use too much computing resources and electricity. The literature analysis reviews and examines current robotic security issues and vulnerabilities, compares used communication methods. Secure communication in the method prototype is implemented using two types of protocols - HTTP and MQTT. The results are presented in the experimental study, which compares the security levels modifications of the protocols, use of calculation resources, speed, additional data overhead and the amount of electricity consumed.

The aim of this paper is to present a realization of a device for displaying, monitoring, and recording non-electrical quantities relevant to the determination and examination of weather conditions. The main unit of this device is the Arduino platform, which controls digital sensors and the GSM module used for communication with user. To accomplish that, the GSM module responds to SMS with the current values of parameters that are being monitored. Also, it uses the GPS service, which allows an Internet connection and sends data back to the Web application. When the Web application receives these data, it processes them and saves them in a MySQL database. The device has the ability to record data on an SD card. A user application is created in C# programming language and allows reading of the recorded data from the SD card and handling of such data. All of results obtained by this device is compared with the results gathered by the Republic Hydrometeorogical Service of Serbia.

O presente trabalho é o resultado de uma intervenção pedagógica realizada em duas etapas denominadas Estudo Piloto e Curso para Professores e Profissionais da Educação, entre os meses de maio e outubro de 2016, com alunos do segundo ano do Ensino Médio, professores e outros profissionais que trabalham na educação formal. O objetivo da pesquisa foi avaliar as possibilidades de inserção da Plataforma Arduino no Ensino de Ciências da Educação Básica através de um enfoque nos conceitos introdutórios de lógica de programação e montagens de circuitos eletrônicos. A pesquisa faz uma avaliação da aprendizagem embasada na Teoria da Aprendizagem Significativa de David Ausubel e verifica duas condições importantes que são: a construção de um material instrucional potencialmente significativo e a predisposição dos aprendizes para incorporar um novo conhecimento. A fundamentação metodológica utilizada foi do tipo intervenção pedagógica, na acepção de Damiani et al., com abordagem predominantemente qualitativa e está dividida em: método de intervenção pedagógica, composta por uma descrição detalhada sobre a intervenção e o método de avaliação da intervenção, que detalha como ocorreu o processo de intervenção através da análise dos dados e dos instrumentos utilizados para obtenção destes. O Estudo Piloto contou com a participação de alunos do segundo ano do Ensino Médio e o Curso para Professores e Profissionais da Educação com dez participantes. A descrição detalhada dos encontros realizados na intervenção pedagógica; a verificação dos objetivos de aprendizagem e os achados da intervenção propriamente dita, conforme discutido por Damiani et al., compõe os resultados e discussões. A experiência didática realizada nas duas etapas ainda integra a elaboração de um produto educacional que poderá servir de base para outros professores em atividades introdutórias sobre a Plataforma Arduino e dos conceitos que ela demanda, seja para a aquisição automática de dados em experimentos de baixo custo ou para formação de professores que necessitam de subsídios para começar a trabalhar com programação, eletrônica ou automação na Educação Básica. Conclui-se ao final deste estudo que as atividades desempenhadas têm forte influência dos conhecimentos prévios relacionados à lógica de programação e ao entendimento de circuitos elétricos. Sem isso, as práticas utilizando tecnologias baseadas na integração de programação e eletrônica continuarão a serem reproduzidas nas escolas, mas pouco compreendidas. Como perspectivas futuras, é apresentado um conjunto de onze recomendações para embasarem novas investigações, principalmente as que tenham como cerne de pesquisa os meios de inserir conceitos introdutórios de programação e eletrônica em currículos da Educação Básica. The present work is the result of a pedagogical intervention carried out in two stages called Pilot Study and Course for Teachers and Professionals of Education, between May and October 2016, with second year high school students, teachers and other professionals who formal education. The objective of the research was to evaluate the possibilities of insertion of the Arduino Platform in the Teaching of Sciences of Basic Education through a focus on the introductory concepts of programming logic and assemblies of electronic circuits. The research evaluates learning based on David Ausubel's Significant Learning Theory and verifies two important conditions: the construction of a potentially significant instructional material and the predisposition of learners to incorporate new knowledge. The methodology used was pedagogical intervention, in the sense of Damiani et al., With a predominantly qualitative approach and is divided into: a pedagogical intervention method, composed of a detailed description of the intervention and the evaluation method of the intervention, which details as the intervention process occurred through the analysis of the data and the instruments used to obtain them. The pilot study counted on the participation of second year high school students and Course for Teachers and Professionals of Education with ten participants. The detailed description of the meetings held in the pedagogical intervention; verification of learning objectives and the findings of the intervention itself, as discussed by Damiani et al., compose the results and discussions. The didactic experience realized in the two stages still integrates the elaboration of an educational product that can be the basis for other teachers in introductory activities on the Arduino Platform and the concepts that it demands, either for the automatic acquisition of data in experiments of low cost or for training teachers who need subsidies to start working with programming, electronics or automation in Basic Education. It is concluded at the end of this study that the activities performed have a strong influence of the previous knowledge related to the logic of programming and to the understanding of electric circuits. Without this, practices using technologies based on the integration of programming and electronics will continue to be reproduced in schools, but little understood. As a future perspective, a set of ten recommendations is presented to support new research, especially those that have as a background the means to introduce introductory concepts of programming and electronics in curricula of Basic Education.

V diplomski nalogi opisujemo nadzorno enoto, ki bo vinarjem prihranila čas pri pretakanju mošta ali vina. Nadzorna enota je na eni strani sestavljena iz elektro omarice in dveh stikal –pretočnega stikala za merjejnje količine tekočine in nivojskega stikala za nadziranje vklopa in izklopa črpalke. Oboje komunicira preko kabla s platformo Arduino. Na drugi strani preko bluetooth HC-06 modula pošiljamo odčitane podatke s senzorjev na aplikacijo na telefonu, kjer lahko spremljamo količino tekočine v cisternah. Nadzorna enota je splošen model in ne velja samo za črpalko, ki smo jo uporabili pri projektu. Važno je le, da je črpalka enofazna. The graduation thesis describes a control unit that will save time for wine producers when pumping must (a wine making term which means unfermented grapes, in nonprofessional’s terms), or wine. On the one hand, the control unit is composed of an electrical box and two switches. First, a liquid flow switch for measuring the liquid level and the second, a level switch for controlling the turning on and off of the pump. Both switches communicate via cable with the Arduino platform. On the other hand, bluetooth HC-06 module sends data readings from switches into the app on the phone, where the amount of liquid in the tank is monitored. The control unit is a generic model and does not apply only to the pump, which was used in the project. It is also, of utmost importance that the pump is single-phased.
