Design and Application Mode of Micro Class Design for PWM Speed Regulating of DC Motor

This paper designs a comprehensive experiment for two important knowledge points, timer and interrupt, in course microcontroller practice technology. To improve teaching effect, we develop related micro class scripts and micro class video, planning to build a micro class digital integrated platform architecture, and puts forward the three stage application model for experiment teaching. The practice proves that the teaching PWM speed regulating of DC motor lesson in this paper has the advantages of improving the efficiency of teaching, improving the quality of teaching and cultivating students' autonomous learning habits.
