Design of Mobile Phone Holder Based on Face Recognition

In this design, the STM32 development board is used as the main control panel of the bracket, the Face _mesh model based on the Mediapipe framework is used for face recognition, the device and the main control circuit are transmitted through the serial port communication of the single-chip microcomputer, and the servo motor SG90 module is controlled by sending PWM signals through the STM32 chip, to achieve the mobile phone holder control design based on face recognition. The experimental test results show that the design completes the interaction process from the terminal to the motherboard and from the motherboard to the motor, and realizes the design goal of completing the control of the mobile phone holder through face recognition. This design has a certain reference value for the design of smartphone holders.
