First, Professor Zhang briefly introduced the content of the training— the course uses the Arduino UNO R3 development board as the hardware platform and adopts the “CDIO model, project-driven” approach for teaching activities. Professor Zhang particularly explained the meaning of “CDIO”: “C” stands for Conceive, “D” stands for Design, “I” stands for Implement, and “O” stands for Operate. This teaching method allows students to actively and practically learn and acquire engineering capabilities through the organic connections between courses, including personal scientific and technological knowledge, lifelong learning ability, communication, and teamwork skills.

Then, Professor Zhang introduced the basic concepts of microcontrollers, microcomputer systems and their basic components, the core part of microcontrollers, and CPUs, along with many resources and websites for learning Arduino, guiding students in their self-study after class.

Halfway through the course, Professor Zhang compared the familiar C language with the Arduino language, clearly and understandably explaining the structure and common functions of the Arduino language, allowing students to gain a preliminary understanding of the language. He also demonstrated experiments with RGB LEDs and infrared obstacle avoidance sensors, letting students experience the fun of Arduino development.

Finally, Professor Zhang encouraged students to team up for project development, providing reference for project topics and suggesting that they choose topics based on personal interest in control systems or IoT applications. He encouraged everyone to design, build, and test projects with their own hands to deeply understand the practical application of classroom knowledge. He also hopes that after project completion, students can showcase and share their results.
