Abstract

This paper mainly completes the hardware platform and software design of the wireless car control system. Hardware platform design using modular design ideas, at the same time, using ARDUINO UNO R3 module as the main control part, ultrasonic sensor module, Bluetooth module, bee sound alarm module, motor driver module as the main modules; software development and design uses ARDUINO programming to write the main program, realizing the car Bluetooth wireless control and automatic ultrasonic obstacle avoidance. And it also uses top-down design ideas. Buzzer alarm module is aim to achieve the automatic obstacle avoidance when the obstacles are close to the car. Ultrasonic distance measurement module HC_SR04 is aim to measure the distance of obstacles and the car, and then to achieve the perception of obstacles. The Bluetooth module HC_05 is used to realize the communication between the control terminal and the control center. Motor drive module L298N for the motor drive is the driving force for the car parts.
