“…First, we have studied the range of voltages at the audio port when a sinusoidal wave is generated with Physics Sensors Toolbox Suite [23]. For this purpose, we have used a conventional oscilloscope (model Tektronix TBS 1072B-EDU) to measure the amplitude of the electromotive force (ε max ) for each step of the volume button of the smartphone.…”

“…Here we make it simple by using the Tone Generator option available in the free app for Android Physics Sensors Toolbox Suite [22]. Another way of turning a smartphone into an oscilloscope takes the advantage of Arduino boards to communicate with a smartphone using the Bluetooth interface, [23] which is a valuable option for smartphones not including a headphone port.…”

This article presents a novel method for studying RLC series circuits using two smartphones, one used as a signal generator and the other as an oscilloscope. We measure the voltage at the external resistor as a function of frequency when subjected to a sinusoidal electromotive force. The experimental results demonstrate a remarkable agreement with the theoretical curve for the voltage at the resistor and the resonance frequency, validating the accuracy of the smartphone-based setup. The experiment fills the gap in educational materials related to electrical circuits and provides a portable alternative to traditional, expensive laboratory equipment.

“…The role of smartphones as oscilloscopes was first proposed by Forinash and Wisman [6] using the headphone port designed for connecting an external microphone and speakers to receive data from an external circuit. Another alternative to transform smartphones into oscilloscopes takes the advantage of using Arduino boards to communicate with a smartphone using the Bluetooth interface [11]. This approach can be used even in the case of smartphones which do not include headphone port.…”

Simple, portable and low-cost experiments as RC and RL series circuits are proposed to experiment with DC circuits. Very common elements are used: a few electronics components (resistors, capacitors, coils and connecting wires) and two smartphones. We consider the charging and discharging of a capacitor in the RC circuit and also that of coil in the RL circuit. Using a smartphone as an oscilloscope we observe voltages variations which are the transient response to a square signal generated in the second smartphone. These voltage variations are directly related to the electrostatic or magnetic energy stored in the circuits. The experimental data have been collected with the smartphone used as an oscilloscope and corroborated with theoretical predictions based on Kirchhoff's laws. The comparison showed differences of the order of the 1% or less between the calculated capacitance or inductance compared to the manufacturer values. This approach which avoids the use of expensive signal generators, oscilloscopes, or any specialized hardware can be performed in less-favored contexts and even as a home assignment.

In recent years, do-it-yourself microcontrollers and sensors have gained increased attention as measurement devices for physics teaching (see, for example, Refs. 1-5). This is not surprising, since Arduinos are relatively cheap and ubiquitous, the code base and design are open source, and there is a wide variety of sensors available. Arduinos can be directly coupled to analysis programs on personal computers and smartphones. This article presents another way of using Arduinos for measurements, namely as portable, standalone devices that store their data on SD memory cards.
