一个简单的音乐原文件，有兴趣的朋友可以参考一下，并修改为自己喜欢的音乐

注:protel电路图 1.INPUT12为高压气压和低压压传感器输入端. 2.OUTPUT为充气输出控制端. 3.当高低压有接地信号时,电机正转,气阀打开. 4.INPUT2低气压时有信号时,充气OUTPUT输出,充气电机转. 5.RS1与RS2是调节阀门距离用地 6.RS3是与气阀电机同步时,是气阀电机的转动圈数传感器. 7.RS4是调节延时时间用地-Note: protel circuit 1.INPUT12 and low-voltage high-pressure pneumatic pressure sensor input. 2.OUTPUT output control for the inflated side. 3. When the high and low pressure have a grounding signal when the motor is transferred, the valve opens. 4.INPUT2 low pressure when there is signal output OUTPUT inflatable, inflatable motor switch. 5.RS1 and RS2 is the regulator valve from the land 6.RS3 synchronous motor with the valve, the valve motor is rotating circle the number of sensors. 7.RS4 delay time to regulate land
