# Main function description

## Bluetooth remote control

* Schematic design
! [Bluetooth.png] * Function implementation
1. Hardware: [ Uxin Electronics] Bluetooth 3.0 module SPP transparent transmission is compatible with HC-05/06 slave JDY-31
2. Software: Bluetooth app design website http://app.gzjkw.net/login/

## Intelligent obstacle avoidance

* schematic design
![Ultrasonic.png] * Function realization
1. Hardware: HC-SR04 new version of ultrasonic ranging module wide voltage 3-5.5V industrial grade sensor
2. Principle: realize intelligent ranging through ultrasonic module, and then control the movement trajectory of the car

## Infrared Tracking

* Schematic design
! [Tracking.png] * Function implementation
1. Main components: ITR9909, LM393
2. Principle: ITR9909 infrared emitting diode continuously emits infrared rays. When the emitted infrared rays are reflected by objects, they are reflected by the infrared receiver. Just accept it and output the analog value. The output simulation value is related to the object distance and object color. By calculating the analog values ​​of the five outputs, the position of the tracking line is determined.
