Trabalho de Conclusão de Curso (Bacharelado em Engenharia Elétrica)- Escola de Engenharia Elétrica, Mecânica e de Computação, Universidade Federal de Goiás, Goiânia, 2023.http://repositorio.bc.ufg.br//handle/ri/24176Currently, most residential appliances have electrical devices that have well-defined properties. These are the scope of study of countless electrical engineering students. Even if these devices are easy to handle, the studies of the systems and devices that compose them require an in-depth analysis, and to carry out this analysis the use of measuring instruments is essential. Some of these devices are known, such as the multimeter, voltmeter, ammeter and oscilloscope. These devices are very ef icient and have a range of utilities, as well as being very precise, showing the indication of one or more characteristic parameters, such as ef ective value, peak value and frequency of magnitudes such as voltage and current. Therefore, it is clear that the oscilloscope’s acquisitiont is mandatory for engineering students, so this document presents the operating principles of the oscilloscope and a basic model made with the use of common software and devices frequent in laboratories and research rooms. of engineering schools. Furthermore, the development of this oscilloscope is intended to collaborat with the practice of research and study in the laboratory.porAcesso AbertoOsciloscópioArduínoFunção de transferênciaCircuito RCPythonServo motorProgramaçãoComunicação serialTaxa de amostragemConversor A/DRegressão linearAnálise de dadosMATLABSistemas de controleTCC
