This article describes the construction and application of a low-cost experimental prototype, based on the Arduino platform.

The prototype provided real-time data acquisition, in a class with undergraduate physics, enabling the visualization of the phenomenon and data sharing with students. Its operation is based on piezoelectricity, which allowed to graphically observe the proportionality between the kinetic energy in each collision and the intensity of the electrical signal obtained.

Entre os desafios impostos pelas restrições causadas pelo covid-19, podemos destacar, em particular, a adaptação de atividades experimentais na modalidade remota. Este artigo descreve a construção e aplicação de um protótipo experimental de baixo custo, baseado na plataforma Arduino. O protótipo foi utilizado em uma aula prática para determinação do coeficiente de restituição em uma colisão inelástica, entre uma bolinha de borracha e uma superfície de madeira. O protótipo forneceu aquisição de dados em tempo real, em uma aula com graduandos em física, possibilitando a visualização do fenômeno e o compartilhamento dos dados com os alunos. Seu funcionamento é baseado na piezoeletricidade, o que permitiu observar graficamente a proporcionalidade entre a energia cinética em cada colisão e a intensidade do sinal elétrico obtido. Os resultados experimentais mostraram baixo desvio padrão e boa consistência em diversas repetições. Também foram comparados com outros resultados, obtidos por uma técnica com utilização de vídeo, mostrando uma concordância da ordem de 2 %.

Among the challenges imposed by the restrictions caused by the covid-19, we can highlight, in particular, the adaptation of experimental activities in the remote mode. This article describes the construction and application of a low-cost experimental prototype, based on the Arduino platform. The prototype was used in a practical class to determine the restitution coefficient in an inelastic collision, between a rubber ball and a wooden surface. The prototype provided real-time data acquisition, in a class with undergraduate physics, enabling the visualization of the phenomenon and data sharing with students. Its operation is based on piezoelectricity, which allowed to graphically observe the proportionality between the kinetic energy in each collision and the intensity of the electrical signal obtained. The experimental results showed low standard deviation and good consistency in several repetitions. They were also compared with other results, obtained by a technique using video, showing an agreement in the order of 2 %. |
