As a method to help current students understand and further improve their interest in the subject of drafting, we have attempted to materialize design problems that have been considered useful for a long time by using a 3D printer. For example, as reported in a previous report, we have embodied a spindle head (gearbox) of a lathe and had students experience gear shifting by sliding gears by hand on a rotating gearbox model. This has often resulted in students being impressed by the operation of the gearbox. On the other hand, it lacked the persuasive power to make the students realize that the speed of the transmission changes according to the gear ratio, in accordance with the design theory that they had worked so hard to calculate. In terms of current mechanical products as a whole, there are few devices that operate only by simple mechanical mechanisms, and electronic control has become indispensable for engines, transmissions, and other devices that require high performance. In educational institutions, simple microcontrollers such as Arduino and Raspberry PI are used to supplement such electronic control in an educational way. In this paper, we attempt to promote students' understanding by using these microcomputer devices to reinforce the educational materials which are only simple mechanisms of machines.
