此次设计采用MSP430单片机作为控制核心，由L298N电机驱动模块来控制小车的运动轨迹，利用超声波模块进行与障碍之间距离的检测，还使用了红外避障模块对障碍进行检测，最后使用了LCD1602显示屏对数据进行显示，以提示驾驶员。整个系统先由电机驱动模块控制小车移动，期间由红外避障模块进行障碍物检测，如果检测到障碍，超声波模块则开始测量距离并显示在LCD液晶屏上，并且小车停止移动。(This design uses the MSP430 MCU as the control core, the L298N motor drive module controls the track of the car, uses the ultrasonic module to detect the distance between the obstacles, and uses the infrared obstacle avoidance module to detect the obstacles. Finally, the LCD1602 display screen is used to display the data to prompt the driving. Clerk. The whole system is controlled by the motor drive module, and the obstacle detection is carried out by the infrared obstacle avoidance module. If the obstacle is detected, the ultrasonic module begins to measure the distance and displays it on the LCD LCD screen, and the car stops moving.)
