Abstract:Resumo Neste trabalho foi desenvolvido um aparato para estudo do som emitido por cordas vibrantes utilizando a plataforma Arduino. Cordas de aço e nylon foram fixadas a um dispositivo que permitia aplicar uma força de tração às cordas e investigar a relação entre esta força e a frequência do som emitido utilizando em conjunto com o Arduino, respectivamente, um sensor de força baseado no módulo HX711 e um sensor de áudio baseado no circuito MAX4466. O sinal de áudio foi obtido a partir da conversão analógico-di… Show more
“…As in other works in the literature, such as Admiral (2020b), the results of the data collected using Arduino were well compatible with what was expected in theory. In a complementary way to the methodology used by Sousa et al (2020), also using Arduino, but for a wave on a string, has a very interesting degree of precision in the experimental results. In relation to the experimental results from the apparatus, we can highlight the practicality obtained by displaying the information graphically, and in real time.…”

“…The use of Arduino for teaching Physics has been widely documented in the literature, particularly with works that involve the understanding of Mechanical and Electromagnetic Waves, as in the works of Admiral (2020a), Admiral (2020b), Sousa et. al.…”
This work aims to use music as a teaching tool and, alongside it, utilize Arduino as a device to verify the components to be studied. The theoretical framework to be used is based on the Potentially Meaningful Teaching Units, UEPS approach, allowing for the construction of meaningful learning for students through problem-solving situations. A didactic sequence was developed for the study of the theme of sound waves and their components at the high school level. This sequence was applied over a period of four weeks, including an initial presentation of topics related to waves, the construction of an electronic system using Arduino, and the verification of phenomena based on musical notes. The data collection instruments for this research included questionnaires to assess students' prior knowledge, mind maps, and exercise lists. The Arduino programming board, which allows for the digitization of analog and digital electrical signals, was used in conjunction with a microphone module, enabling the integration of electronic physics with wave physics. As a result of this research, there were indications of learning through the interdisciplinary relationship between music and physics, which was made effective through the use of Arduino and the recorder flute.

“…Sua principal vantagem é sua prática silenciosa, produzindo menos ruído do que tambor tradicional, sendo ideal para estudos. Usamos a plataforma Arduino, pois a própria facilita a concepção e a realização de experimentos de Física por disponibilizar o software e o hardware que permitem o controle e o processamento de dados obtidos a partir de sensores externos, ou mesmo em suas portas I/O [2].…”
Microcontroladores são dispositivos equipados com uma unidade de processamento, que em combinação com sensores, são capazes de realizar experimentos físicos. Nesse trabalho nós construímos um tambor de bateria eletrônica de duas zonas, utilizando sensores piezoelétricos como triggers controlados por uma placa Arduino. Fizemos experimentos para caracterizar os sensores e otimizar a sua integração a um tambor equipado com uma pele muda, de forma que o tambor não emite som expressivo quando atingido pela baqueta, mas torna-se um controlador MIDI percussivo. O resultado é um sistema econômico, estável e funcional para a prática e execução musical, sendo também de interesse para o estudo da Física Aplicada.
