Resumo

This work presents two electronic systems experiments with resonance tubes, which generate automatically a sequence of several sound wave frequencies in a range defined by the user and then verifies the amplitude of each one in real-time, allowing for the immediate data visualization in a graph. Besides, they save all the frequency values and the respective wave amplitudes in a text file that can be later imported and processed with worksheets. The final results were satisfactory and this work explains all the hardware and software aspects based on an open-source philosophy.
