说明：  Arduino编写的智能车控制程序源码，使用串口与计算机进行数据交换，通过计算机在线控制智能车运动并读取智能车当前时刻的状态参数
(State parameters of the the Arduino write intelligent vehicle control program source code, use the serial port with the computer for data exchange and online through computer control intelligent vehicle movement and read the current time of the smart car)
