Design of Music Toy Car Based on Smart Phone Via Bluetooth Remote Control

This design is based on the STM32F103C8T6 microcontroller and UCOS-II operating system. Including the microcontroller module, the MP3 player module, the motor drive module and the Bluetooth transceiver module. Each sub-module assigns different priorities through establishing different tasks, each task delivers messages through the message mailbox, in order to achieve the coordination of the various sub-modules. The design uses two AA batteries for the main control module and other sub-modules for power supply. Controlling is based on the smart phone's Bluetooth function, through the mobile App to send the task instructions to achieve the smart car of different ways of movement and music playing function.
