循迹智能小车，pwm脉宽调制调速实现转弯，四路传感器-Intelligent vehicle, PWM pulse width modulation control to realize turning, four sensors

我平时自己研究的智能循迹小车。三个传感器。可扩展。不带PWM直流电机调速。-I usually do their own research intelligent tracking car. Three sensors. Scalable. Without PWM DC motor speed.

自己搜集的智能小车，包括循迹，红外探测，pwm测试程序-th collect smart car, including tracking, infrared detection, pwm test procedures, etc.
