本迷宫小汽车选用8位STC90C52单片机为控制器，通过3个红外光电传感器E18-D80nk对信号进行采集，采集到的信号经串口转换MAX232CPE处理后传给STC90C52单片机，经单片机处理后，发出控制命令给L298N，驱动2台直流电动机进行相应的动作。该小车实现了前进、后退、左右转弯、避障以及显示运行时间等基本功能，整个系统结构简单，可靠性高，实验测试结果满足要求-STC90C52 microcontroller pass the maze of car use 8 STC90C52 single-chip controller, acquisition by three infrared photoelectric sensor E18-D80nk signal acquisition to signal through the serial port conversion MAX232CPE processing processed by the microcontroller, issue control commands L298N drive 2 DC motors corresponding action. The car forward, backward, left and right turns, obstacle avoidance and display the basic functions of the operating time, the entire system of simple structure, high reliability, and experimental test results meet the requirements
