The Physical computing and Coding education are receiving a lot of attention in various fields. In the educational field, the need for education utilizing Physical computing and Coding education are also being emerged. In this study, we have created a new type of the Arduino−Neutralization Titration experiment device that is operated by manipulating the code. The traditional neutralization titration experiment uses indicator or pH meter to calculate the concentration of acid and base. The indicator do not have a constant discoloration because it cause accidental error and is not manufactured in the same environment. And the pH meter cannot operate the program inside the device, so only simple measurement is possible. However, the Arduino−Neutralization Titration is designed with LED and pH sensor, and the LED acts as an indicator as color changes depending on the pH value. In addition, this device has a discoloration range of three indicators, allowing you to select the indicator depending on your experiment. Above all, students can understand scientific concepts while interpreting code, and can easily manipulate code, enabling various thinking. Therefore, we would like to suggest that the Arduino−Neutralization Titration be used at schools to enhance students' understanding of scientific concepts and to help expand their thinking.
