- Abstract
In this work we present the construction of a device for determining electrical impedance using embedded systems. Specifically we use two Arduinos, both of Nano Arduino, and an Digital Analog Converter (DAC). The first Arduino, together with the DAC, has the function of generating a harmonic signal that allows the frequency varies in the range of 2 Hz up to 120 Hz. The second Arduino is responsible for performing measurements of electrical voltage, electrical current and electrical impedance of the system in interest. In addition, the experimental activities had a greater emphasis on applying at this platform all learnings that the students reach during the course until the now, that were taught in theory classes. Using this knowledge, the experiment was built. The applied methods proved to be efficient for the construction and acquisition of data obtained during the impedance measurements.
