The short message control of the smart car motion based on the MCU

TC35 based on Siemens GSM wireless communication module and STC microcontroller debugging system is introduced in this paper. The basic functions of TC35 settings is mainly described. The control for the TC35 module is realized via the serial communication between the MCU and TC35 board. That is, according to information received by TC35 module, through the communication with MCU, the MCU decodes and executes the corresponding action to control the car. In the car aspect, the main task is designing four H bridge circuit to drive motor, as well as the function of RPR220 tracking sensor and the design of corresponding driver circuit, and the application of photoelectric switch.
