Problems solved by technology

[0003] When the existing technology is used, when using equipment for teaching, it is necessary to use a projector to project the teaching tools used in the teaching process, and when there are too many teaching tools or materials to be displayed, the teacher needs to continuously operate the projector, and It can only stay near the teaching desk, which affects the quality of teaching and needs to walk back and forth between the blackboard and the teaching desk. It is very unchanged and needs to be improved
