DIY Line Tracking Ultrasonic Obstacle Avoider Robotics Car Kit

This product is a smart car developed based on UNO R3, which can realize four-way tracking function and ultrasonic obstacle avoidance function.

 

There are mainly four modules, including infrared signal detection module, main control module, motor drive module, and ultrasonic sensor module.

 

The smart car adopts a welding-free installation design. The components are fixed by copper pillars and screws. The circuit connection between each module is connected by DuPont wire, which is simple and convenient.

 

Features

  • The main control board adopts CH340 UNO R3 development board.
  • The motor drive module uses a typical L298N module to drive a DC motor.
  • The infrared signal detection module uses four infrared light pairs to detect the black line and realize the tracking function.
  • The ultrasonic sensor module uses the HC-SR04 module, through which the distance is measured, so as to realize the ultrasonic obstacle avoidance function.
