[LiChuang Development Board] Tracking car based on Liangshan School

  The smart car is a very classic course case. There are various car models and kits on the market. Can we design a smart car by ourselves? Based on this idea, I used the Liangshan School made by the gd32f470 chip to make this tracking car.
Function introduction:
two left and right headlights to simulate the status of the headlights in driving
. Independent buttons to practice key input and interrupt functions. Passive
buzzer to learn the generation of audio frequencies and simulate the music of a sprinkler truck
. Four motor drivers to achieve PWM output and speed regulation
functions. Tracking and obstacle avoidance functions to learn comparator circuits to achieve obstacle avoidance and tracking functions.
Wireless remote control to learn wireless transmission theory to achieve remote control functions.
Additional functions: Tracking function is achieved by adding a camera.
