Abstract In this era of 4.0, elementary school student education has been involved in simple robotic learning, such as line follower, line follower, and other robotics, mostly there is a voltage divider circuit. A voltage divider circuit is a form of many resistor configurations. The circuit is straightforward: it is constructed by a DC source (for example, Battery, Power Supply) as the input voltage (Vin), and at least two resistors (named as R1 it must follow commercially available resistors. A user-friendly, attractive, and simple calculation tool is needed to facilitate finding these variables. Based on literature studies, there has not been found in any paper that explicitly discusses the Android-based Voltage Divider Calculator. We also found no results for finding the applications mentioned on the sites of commercial Application providers (such as Playstore, Appstore, and so on). This paper is a preliminary study in designing an Android-based Voltage Divider Calculator Application. This paper only presents the analysis and design steps. It is hoped that this application can later be used as a complementary tool in the elementary school level electronics extracurricular program because most of the electronic material taught to elementary school students contains the introduction of resistors and mathematical expressions of resistor configuration accompany their application.
