电机不转，按下启动键，电机旋转，速度为25转/分，按下加1 键，速度增加，按下减1 键，速度降低，最高速度为100 转/分，最低转带为25 转/分，按下停止键，电机停转。速度值要求在数码管上显示出来。-Motor does not turn, press the start button, motor rotation speed of 25 rev/min, press the 1 key, the speed increase by 1 press the button to lower the speed, the maximum speed of 100 r/min, with a minimum of 25 to r/min, press the stop button to stop motor. Speed value of the requirements in the digital tube display.
