Experimentos de física moderna para a determinação da constante de Planck utilizando Arduino e Visual Basic: uma alternativa na formação e na prática docente

Abstract

The following work is reasoned on the development of new technologies into the teaching of physics with emphasis on the teacher’s formation and your practice in the classroom, debating the detailed construction of equipment with a low cost but with a good precision, focused on the teaching of Modern Physics. The prototypes that are developed are derived of equipment that are already known, however, the new electronical structure and computational that are associated to them, turn them more interactive and easy to operate. In this work, we developed two equipment. The first one (The Automated Spectrometer) it is used to measure the length of the wave that is issued by a LED diode, the second one (The Planck), is intended to determine the value of Planck’s constant, through this same electronical component. Those equipment are connected to an interface of prototyping called Arduino, that promotes its communication with a computer. The data collected are analyzed by a software developed with Visual Basic language, providing the desired results. Comparing to other works throughout the text, we can observe that both present significantly accurate results and can be used to explain related Modern Physics’ phenomena. Following the itinerary of utilization and operation of the equipment, associated to the discussion of the phenomena presented in the theoretical reference of this work, it’s possible to develop practices that can integrate all the addressed themes. Teachers and graduating students can use those equipment with success in High School classrooms, laboratories teaching experimental physics and in lectures in college majors.The additional material works as construction guide and project development, presenting threedimensional models of the components, electronical circuits and software’s’ source codes. The material contained in this work can serve as support in the development of a series of new applications.
