Estudo de plataforma de prototipagem para montagem de um sistema de aferição de massa para uso didático

Abstract

The present work aims to develop a study on the Arduino prototyping platform for further development of a project for mounting a balance. To do this, we will start with physical concepts related to the operation of general electrical circuits, which will be necessary to understand how the mass sensor collects the data. Next, the primary programming structure of the Arduino platform will be described, starting with the presentation of the Integrated Development Environment (IDE) software and its main features. Later we will detail the hardware structure of the Arduino platform, explaining the function of each of its electronic components. After understanding the operation of the Arduino platform, we began the development of the mass measurement system project. At first, we describe the assembly of the electrical and mechanical components of the balance prototype. Then the zero-point calibration is made, and the conversion constant measured from the load cell deformation. This constant value will be used to convert the measurements made by Ardu´ıno to mass units. Finally we selected a set of 16 objects with known masses to validate the prototype developed in this work. In the end, we present the results of comparative data analysis and also the feasibility of using this prototype for educational purposes.
