Experimental kit for studing real-time oscilations using arduino

The study of oscillations can be configured as a rich opportunity for the development of experimental activities. However, due to a series of instrumental difficulties, many teachers choose to work only with a stopwatch to obtain the average frequency of the oscillations. To obtain from the data of position versus time is generally available for those who have access to expensive experimental kits. In this article we propose the construction and use of an experimental kit for study of oscillations using arduino, as well as a proposal of use. With a ultrassonic sensor HC-SR04, we can construct real position graphs, allowing a visualization of the sinusoidal behavior visualized in the theory, and also enabling a greater understanding of the phenomenon and the determination of the physical quantities involved. The kit includes a software developed in C + ⁣ + , called PMOscillator, responsible for the acquisition, processing, real-time plotting and data analysis.
