Aiming to the problems of few mouse types, cumbersome renting and difficult management in internet bar, the design of an intelligent sharing mouse cabinet based on Arduino and app inventor is proposed. The mouse cabinet has three layers and each layer has a different type of mouse. A distance sensor is set at the center of each layer, and the value of the distance sensor is used to judge whether the mouse is taken out or not. Stepping motor is adopted to drive the baffle to complete the control of the mouse line. Each layer is equipped with a red and a green light emitting diodes. When the red-light emitting diode is on, it means that the mouse is borrowed. When the green-light emitting diode is on, it means that the mouse is returned. The cabinet door has two modes: left-open mode and right-open mode. The red-light emitting diode on the left side of the top layer indicates that the door opens left, the red-light emitting diode on the right side of the top layer indicates that the door opens right, and the green light-emitting diode on the top layer indicates that the door closes. cabinet door switch is controlled with steering gear and stepping motor. App Inventor 2 is used as a tool to realize the design of mobile APP. Users can rent the mouse through the APP and scan the user"s rental and mouse usage in the server. This intelligent sharing mouse cabinet has the characteristics of low cost, easy realization, and expansion. It can be used for the transportation confrontation competition and as the reference of the robot design and practice. It also has practical application value.
