Portable Buzzer Circuit Design for Reform of Electronic Technology Experiments

As an important practical course in the field of electrical and electronic engineering, Electronic Technology Experiments not only reflect the students' familiarity with theoretical courses but also lay a solid foundation for subsequent specialized courses and post-graduation work. At the same time, it allows students to practice and test their theoretical knowledge of analog and digital electronic technologies. Through a complete project-based experimental approach, our Information Engineering Experiment Center has targeted comprehensive and exploratory reforms for both analog and digital electronic technology experiments. From the perspective of the reform outcomes, students' interest in experimental learning, project thinking skills, practical abilities, and innovative capabilities have all been significantly enhanced. This article uses the design of a pocket-sized quiz buzzer circuit as an example to elaborate on the basis of the reforms.
