Design of Automatic Light Searching Car Based on Photosensitive Sensor

Based on STC89C52 series single-chip and photosensitive sensor, the intelligent vehicle can sense the direction of signal light and drive towards to it. Moreover, the car can prevent itself from crashing the barrier by using an ultrasonic module. Motors are controlled by the PWM wave function. This design can judge the state of the car and send the corresponding instructions to control the car. Last but not least, the circuit wafers was designed by Altuim designer and the program was designed by Keil uVision4.
