Description:
1. This product is a smart car developed based on the Atmega328p development board.
2. It can realize four-way tracking function, ultrasonic obstacle avoidance function, and car following function.
3. There are mainly four modules:
* LM339 four-channel infrared signal detection module
* main control module
* motor drive module
* ultrasonic sensor module
4. The smart car adopts a welding-free installation design.
5. The components are fixed by copper pillars and screws.
6. The circuit connection between each module is connected by DuPont wire, which is simple and convenient.
Features：
Features：
1. The main control board adopts development board.
2. The motor drive module uses a typical L298N module to drive a DC motor.
3. The infrared signal detection module uses four infrared light pairs to detect the black line and realize the tracking function.
4. The ultrasonic sensor module uses the HC-SR04 module, through which the distance is measured, so as to realize the ultrasonic obstacle avoidance function.
5. The combination of ultrasonic and two infrared detection modules realizes the car following function.
