Abstract: In the course of “Electronic Circuit Design Experiment”, we introduced the Arduino platform, using the Arduino development board as the main controller, and then students designed the main circuit, that is, the Arduino expansion board, and completed the electronic circuit design project through comprehensive joint debugging of software and hardware. The implementation of the teaching project plays a positive role in solidifying the foundation of electronic circuits, inspiring students’ creative vitality, cultivating the spirit of cooperation among students, improving the practical teaching level of electronic circuits and improving the teaching effect.
