RC circuit (Resistor-Capacitor) is an electric circuit that has a combination of resistor and capacitor components which are installed either series or parallel. This research was conducted to measure the capacitance of two capacitors with different capacitances with only using one resistor. This study aims to compare the capacitance both experimentally (using data acquisition systems) and theoretically. Capacitance measurements were carried out experimentally using Arduino Uno and at a maximum voltage of 5 volts. In this research, it has been successfully determined the charge capacitance of the capacitors, both in experiment and theory. It has been found the correlation of the results between experiment and theory (the value of R2 in charging and discharging process is greater than 0.95).

This research was conducted to determine specific heat of pure water and salt solution using the calorimeter measurement method based on the Arduino Uno microcontroller. The salt solution and pure water solution were heated by the heating wire with 2.4 A and 0.54 Ω. The temperature of the pure water and the salt solution was measured using the Arduino Uno microcontroller and DS18B20 temperature sensor. In this study, the Cv of pure water and salt solution has been found.

In this research, a light efficiency test tool has been designed using an Arduino UNO microcontroller to provide an understanding of the use of the ohm law application in basic physics practicum. This lamp efficiency test prototype uses an LDR sensor device and a resistor connected to the Arduino microcontroller as a light intensity detector, while the variation of electrical power is used by an AC variac with the lamp distance to the sensor having a constant value. The experimental results showed that the efficiency of the lamp can be obtained through a gradient of the luminosity curve on electric power. The efficiency of the lamp is 16.935 lm/watt and the average resistance can be obtained on 983.01 which the intensity in lux is 337,05 lux on 157,68 Lm and the maximum intensity in lux can be obtained on 453,35 lux on 208,54 Lm.

Heat rate and heat capacity are widely used to determine the thermal characteristics, especially for wastewater treatment using electro coagulant. This study aimed to determine the value of heat rate and heat capacity of the waste solution in the textile industry, especially in the dyeing waste, by using a microcontroller device. The method for measuring the specific heat capacity and the textile waste solution's heat rate is based on the principle of the first law of Thermodynamics. Temperature measurements were carried out using a digital temperature sensor type DS18B20. In this research, the heat rate and specific heat of the dyeing solution and mineral water used in the textile industry have been studied. This study uses five types of dyeing waste solution as test solutions, namely green waste solution, orange waste solution, blue waste solution, brown waste solution, and mineral water. This experiment's principle is applying Joule's law by using electrical properties with a microcontroller device used to obtain the rise of temperature data each time in real-time every 2 seconds. Based on this research, it can be concluded that the instrument can be used to measure the heat rate and heat capacity of a textile waste solution. Based on this research, we also found that the specific heat of hard water (Hard water is a kind of water with high mineral content, while soft water is water with low mineral content. Apart from calcium and magnesium ions, the cause of hardness can also be other metal ions as well as bicarbonate and sulfate salts) (4.19 ± 0.77) J/ gram ℃ and the specific heat of the four types of waste solution ranged from (3.20 ± 0.72) J/gram ℃ to (6.83 ± 1.71) J/gram ℃ and also it was found that the heat rate of hard water is 0,0471 ℃/s and the heat rate of the four types of waste solution is range from 0,0289 ℃/s to 0,0617 ℃/s.
