In today's world, microcontroller technology is crucial in automation systems across both industrial and everyday contexts. Consequently, vocational education must emphasize the development of practical skills in electrical device control through learning media that prioritize hands-on experience (Learning by Doing) to enhance students' learning outcomes effectively. This study aimed to develop instructional media focused on the application of Arduino for controlling electrical devices at the vocational certificate level at Samut Prakan Technical College. The study also sought to examine students' academic achievement and satisfaction with the developed media. The participants included five instructors from the Electrical Power and Mechatronics departments and fifteen second-year vocational students majoring in Mechanical Engineering and Production Technology, selected through purposive sampling. Research instruments included an Arduino-based demonstration kit, a media quality evaluation form, and a student satisfaction survey. The findings revealed that the developed learning media achieved a high level of quality. Students showed a statistically significant improvement in academic performance and reported a very high level of satisfaction with the learning experience. The developed media effectively enhanced students’ deep understanding and practical skills essential for the electrical field and is therefore suitable for broader adoption in vocational education institutions.
