The course starts with an introduction to electronic components and electronic circuits, explaining the key concepts and practical operations. Integrate Arduino programming and electronic circuits to show the results in the physical world. Enhancing the learning effect also helps cross-field learning and expanding career planning. During the learning process, simulation test questions for the Arduino Certification Program：Fundamentals (ACP) will be added to verify the effectiveness of the learning. At the same time, students can be familiar with the content and format of the actual certification exam questions, and learners have the opportunity to prove and test their abilities, and pass the exam to obtain certification.
