sin()函数 给定一个弧度值或者任意数值，可以计算相应的sin值即正弦值(sin () function is given a value, or any value in radians, we can calculate the corresponding value of the sine value sin)

用三个按键控制pwm输出 key0控制是选着显示/改变频率或占空比 key1控制增加 key2控制减少 数码管显示频率或占空比 频率单位默认Hz（500-20KHz） 占空比范围（0.1-0.9）(Control PWM output with three keys Key0 controls display/change frequency or duty cycle optionally Key1 controls the increase Key2 controls are reduced Digital tube display frequency or duty ratio Frequency unit default Hz (500-20khz) Duty cycle range (0.1-0.9))
