“…We have not used a second smartphone as an oscilloscope as in previous works [5,10] because it does not seem to be possible, to the best of our knowledge, to use a smartphone to visualize two signals at the same time. This is why we have used a conventional oscilloscope instead which also allows to measure small phase shifts accurately.…”

“…The study of these simple circuits has been addressed in very recent works by using smartphones as signal generators and as oscilloscopes where the signals are sent in and out through the audio port by means of a jack connector [5,10]. The smartphone can be turned into a signal generator by using the Tone Generator option available in the free app for Android Physics Sensors Toolbox Suite [11].…”

The measured voltage at the inductor in an RLC series circuit connected to a sinusoidal electromotive force depends on the current and the impedance. The latter does not only include the inductive reactance only but also the ohmic resistance of the inductor. This fact has a clear consequence on the result of the measurement as the measured voltage at the inductor is not in counterphase with the measured voltage at the capacitance as shown in theory where ideal inductors are usually considered. In this work, the resistance of a coil in an RLC circuit is obtained from the direct measurements of the phase of the voltage at the coil at resonance and the resonant frequency for different values of capacitance. This value is compared with the resistance of the coil determined directly with an ohmmeter. The agreement between both values is very good. The conventional signal generator has been replaced by a smartphone which is a very familiar device for the students. The smartphone can provide the necessary voltage supply for the experiment to be carried out successfully.

This research focuses on modifying two physics experiments, a rotating wheel and a simple harmonic oscillator, to train pre-service physics teachers with an emphasis on digital and maker skills. The primary aims are twofold: first, to demonstrate the application of a Hall sensor, combined with the GoGo Board, in determining the angular speed in the rotating-wheel experiment and the angular frequency in the oscillation experiment. The second aim involves comparing these results with those obtained from high-speed video analysis using the Tracker software. To measure the period, a neodymium magnet was attached to both the wheel and mass. A block-based code was developed to control the Hall sensor and record the time when the magnet entered the detectable range of the sensor. In both experiments, high-speed videos at 250 fps were recorded and analysed using Tracker software. The study revealed that while the Hall sensor yields accurate measurements at lower speeds, its performance declines at higher speeds owing to limitations in accurately detecting the position of the magnet. In a simple harmonic oscillation experiment, the Hall sensor proved to be more effective at slower speeds. Although the Hall sensor approach resulted in a higher percentage error, it significantly enhanced students’ learning experience in terms of computational thinking and digital/maker skills.

Mathematical modeling and numerical simulation have a considerable presence in the vast universe of engineering disciplines, given their usefulness in explaining, comprehending, and simulating phenomena and processes with which engineers are in contact in their daily creative and problem‐solving work. For this reason, engineering study programs have at least one course dedicated to dealing with the mathematical modeling of dynamic systems as an essential complement to subsequent courses such as automatic control, structural dynamics, and mechanical vibrations. Nowadays, many technological tools illustrate the applications of mathematical modeling interactively through experiments that offer an incomparable motivation to the students to corroborate with real‐world examples, the utility and veracity of the theory presented to them in the classroom and that in many occasions seems lacking utility and direct relation with the world in which they develop. Based on those mentioned above, this paper presents an example of applying the Laplace transform in modeling physical systems, using a second‐order circuit attached to an Arduino Due board in conjunction with the Jupyter Notebook environment. The numerical and experimental results can be obtained through three optional kernels: Python, Octave, or MATLAB®. For educational purposes, the resulting computer application was presented to undergraduate students of Mechatronics Engineering as an illustrative complement to two courses entitled Signals and Systems Analysis, part of the second semester, and Mathematical Modeling, part of the fifth semester.
