里面有手册和资料，有STM32的简单控制舵机和LED的程序，用的IO口仿I2C(There are manuals and materials in it. There are simple procedures for STM32 to control steering gear and led. The IO port used is similar to I2C)

stm32pwm,做项目控制呼吸灯、舵机等经常会遇到的，所以还是很重要的(Stm32pwm is often encountered in project control such as breathing lamp and steering gear, so it is still very important)

三个电位器控制三个舵机，实现同步机械臂，带动作记忆功能(Three potentiometers control three servos to realize synchronous manipulator with action memory function)
