Intelligent tracking and obstacle-avoid car

Abstract：Based infrared detection of black lines and the road obstacles, and use a STC89C52 MCU as the controlling core for the speed and direction, A electronic drived, which can automatic track and avoid the obstacle, was designed and fabricated. In which, the car is drived by the L298N circuit, its speed is controlled by the output PWM signal from the STC89C52.
