The goal of this study was to determine the level of smart electronic device microcontroller development boards were used as teaching tools (BBM) in Penang secondary schools for the teaching and learning of the subject of design and technology (RBT). The effectiveness of using microcontroller development boards as instructional aids and tools (BBM) based on digital technology might enhance the quality of instruction and learning in electronic design provided by RBT teachers. As a result, this article describes the conclusions of the attitudes of RBT teachers towards fuel usage that were based on a microcontroller development board. To conduct the study, 128 RBT teachers who teach electronic design to Form 2 and Form 3 students in secondary schools were given questionnaires. Statistical Package for the Social Sciences (SPSS) Version 26 software was used to perform a descriptive analysis of the data to determine the frequency distribution, percentage, and mean comparison. T-tests were also run to determine whether there was a gender difference. With an average score of 3.93, the results demonstrate that Form 2 and Form 3 RBT teachers had a moderate attitude regarding the employment of microcontroller boards. The t-test results, however, revealed no gender differences between the RBT teachers' use of the microcontroller board. The same research topics were recommended to be broadened to include students in the future and explore the relationship between teachers' attitudes and the use of microcontrollers from a behavioral perspective in Malaysian classrooms.
