“…Although the measurement of the electrical conductivity of an aqueous solution has been possible since the second half of the 19th century [37], and a wide range of conductivity meter models is currently available [38], it is difficult to find a conductivity meter that fully meets all the particular requirements of, for example, the agricultural sector [39]: ease of use, robustness, real-time data transmission, long-term stability, and, possibly, low cost [40]. At end of March 2023, 17,753 articles on Arduino were indexed on Scopus confirming its application in science as a multi-parameter sensor for marine research [41], but also in education [42]. The prototype for conductivity measures here presented fully meets our aims.…”

Electrical conductivity is one of the main parameters for the characterization of water solutions and for the monitoring of water sources. In this paper, we describe a very inexpensive prototype for conductivity measurements based on Arduino UNO R3 coupled to an open-source circuit board with only passive components. We designed the printed circuit board (PCB) and the suitable handmade cell using stainless-steel electrodes and wrote the freeware management software; the assembly of the prototype, including a temperature probe, and results were relatively simple. In order to allow for replicates, the instrument design, schematics, and software are available with an open-source license. Thirty-one bottles of spring waters with conductivities of between 15.2 and 2000 µS cm−1 were tested using both this prototype and a commercial conductivity meter. Data correlation produced an equation that allowed us to obtain the conductivity value, starting with the value furnished by the Arduino apparatus in arbitrary units. The prototype is accurate enough (inaccuracy lower than 6% excluding very low conductivity values) and precise (RSD% of about 5%). Even if a lot of commercial instruments for conductivity are available, we propose a prototype built with the aim of lowering the cost of measurements, while ensuring that they remain useful for lab or in situ application, as well as for continuous water monitoring/management systems. A further aim was to propose the building of the instrument as a laboratory exercise; this can help students to better understand basic theoretical concepts regarding conductivity, electronic components, and the acquisition and treatment of analytical data.

“…The great advantage of the Arduino microcontroller is that it facilitates designing lowcost, small-scale experiments for verification of diverse physical principles through experiential learning. A recent study [2] has reported the applications of Arduino in different branches of physics to design experiments with new thoughts. Experimental demonstration and analysis of noise [3], large amplitude oscillation [4], and damped oscillation in simple pendulum [5][6][7] are such few examples.…”

The oscillation of a bar magnet along the axis of a closed loop solenoid has been studied quantitatively using an ultrasonic sensor and Arduino microcontroller-based platform. Real-time displacement of the oscillatory magnet with and without the solenoid shows an additional damping effect due to electromagnetic induction in the presence of the closed-loop solenoid. Variation of the induced current in the solenoid circuit has been analyzed over several cycles by simultaneous recording of the voltage developed across two resistors using ‘analogread’ library function. Energy drained from the oscillator due to electromagnetic damping has been compared with the energy lost in Joule heating of the solenoid circuit. A phase plot for the underdamped oscillator was generated using the fitting parameter values of the curve fitted with the position vs. time data points on the plot. This portable and inexpensive microcontroller-based design is well suited for STEM education of high school and for sophomores in an undergraduate physics course.

“…Thus, this study proposes a method for determining specific heat using the Arduino prototyping platform. This choice is motivated by its reliability, affordability, and widespread availability [24][25][26]. In addition, it combines an analytical methodology suitable for materials in both solid and liquid states, aligning more closely with contemporary demands and students' future careers.…”

This article describes a new approach for determining the specific heat of solid and liquid samples in an educational laboratory setting. The experiment employed automated data collection, using Arduino® to record temperatures as the system cooled. Samples of water, ethyl alcohol, lead, and aluminium were analysed by exchanging heat with preheated water in a non-insulated container. To identify the moments when the samples attained thermal equilibrium with the reference liquid, we employed the cooling curve adjusted using Newton’s law of cooling. This correction allowed us to uncover the exact points of equilibrium with enhanced accuracy. The results, both for solid and liquid samples, indicated the effectiveness of the method, due to its reasonable proximity to the expected values (e% < 10). This approach goes beyond the conventional calorimeter, proving its viability in testing various samples and thus enhancing research on the thermal properties of different materials.
