* Note: For simple use ,the upper diagram is ready,But if you find the noise is quite loud, then you could attach an 1K resistor to the TX pin.
* You can download the latest library here: [https://github.com/DFRobot/DFRobotDFPlayerMini/archive/1.0.1.zip DFRobotDFPlayerMini.]
* More demo code please find at https://github.com/Edragon/Arduino/
