Problems solved by technology

[0002] Common blackboards in general classrooms are wiped off by students using black and white blackboards to wipe off the words written on the blackboard during class. When wiping the blackboard, dust flies around. The speed of students wiping the blackboard is slow, and the time between classes is not long. Within a certain period of time, the dust will not completely fall to the ground, and because the students walk around, the dust will be scattered around, affecting the overall environmental sanitation of the classroom
