通过电位器的两端接地和+5v中间抽头接adc，根据adc读取的值在数码管上显示旋转的角度。-Grounded at both ends of the potentiometer and the+5 v intermediate tap connected to adc, adc read according to the value of the digital display on the angle of rotation.

stm32简单步进电机,通过简单延时，使步进电机旋转任意角度，并且通过数码管显示，通过按键输入角度-stm32 simple stepper motor through a simple delay, the stepper motor rotation at any angle, and through the digital display, through the key input angle

基于单片机的步进电机设计，可以在单片机的控制下，实现正反转，以及随意角度的旋转。-Microcontroller based stepper motor design, you can control the microcontroller to achieve positive and negative, as well as arbitrary angle rotation.
