More importantly, it can provide services for people 24 hours a day. Because of this in the relatively developed countries, the vending machine has become a very important retail sales platform. This style of fashion has attracted many customers. This makes the vending machine sales market is growing, there are more businesses are willing to buy. The popularity of vending machines has played a crucial role. In this paper, the single chip microcomputer direct, stepping motor to drive the double helix sent out the structure of the vending machine to do the relevant research.
