Block-Based Development of a Mobile Application in Basic Electrical Concept for Diploma in Electrical Engineering Student

Abstract

Electrical Technology is one of the main courses for Diploma in Electrical Engineering students in Politeknik Malaysia. The subject has been delivered conventionally; however, due to the Covid-19 pandemic, relatively it has changed the landscape in delivery method. Regarding this problem, an innovation by using an online learning application such as mobile applications is a must. There are many mobile applications provided in the Google Playstore; however, the function is either limited to one function for each mobile application or too complicated for diploma students. This paper presents the block-based programming language used in App Inventor to make the creation of mobile apps for basic electrical concepts for electrical engineering students in Politeknik namely My ReSist. This app is used to convert the resistance color codes to resistance values and calculate the total resistance in the circuit as well as to do Star-Delta transformations. Results showed that this mobile application is useful for students to solve basic electrical concept including total resistance in series and parallel circuit. It is proved that this app is user-friendly and attractive.
