CAVALCANTE, Marisa Almeida; TAVOLARO, Cristiane Rodrigues Caetano and MOLISANI, Elio. Physics with Arduino for beginners. Rev. Bras. Ensino Fís. [online]. 2011, vol.33, n.4, pp. 4503-4503. ISSN 1806-1117. http://dx.doi.org/10.1590/S1806-11172011000400018.
In this paper we present different ways of operating the Arduino to work as an alternative interface for the automation of data acquisition in physics experiments through the computer's USB port. Selected as an example of applying the study of charging and discharging a capacitor. The steps of interaction with the Arduino go through the process of building the circuit, collecting and storing data in txt format and graphic display in real time over the language Processing. For each step we present proposals for didactic use, all source code necessary to interact with the Arduino, and links to access tutorials that provide playback of this and other experiments.
Keywords : Arduino; processing; acquisition of data.
