Licheng Liangshan School Smart Car

The hardware

consists of a LCSC Liangshanpai GD32F470 main controller,
an RZ7889 motor driven by a DC geared motor,
an ITR9909 infrared module for tracking (software to be improved),
a Bluetooth external plug-in JDY-31
ultrasonic sensor (obstacle avoidance), and an HC-SR04
PCB. The development process followed LCSC Liangshanpai's video tutorials and took approximately 60 minutes. This also forms the chassis.

The software
uses Keil, with rough C programming
using PWM to control wheel speed and differential steering. A Bluetooth app controls the car's lights, forward/backward/steering, and obstacle avoidance mode, allowing it to reverse and then turn before moving forward again upon encountering an obstacle. The development
was primarily based on Lark documentation and Bilibili videos. During coding, an issue arose where the chip could not be programmed (compilation was normal, but the chip did not work after programming). This problem was solved using the provided project template. Two short videos of the initial setup
are provided : https://www.bilibili.com/video/BV1Lj411L7jj . Finally, I would like to thank LCSC for its efforts in the open-source community and for providing excellent development boards and high-quality learning resources. This is my first time open-sourcing a replica project. If there are any errors, please point them out.
