USB接口

直接使用Keyboard、Mouse等进行操作，使用方法请参考示例：

#include 

void setup() {
  USBHID_begin_with_serial(HID_KEYBOARD_MOUSE);
  delay(2000);
}

void loop() {
  Keyboard.println("UP");
  Mouse.move(0,-127);
  delay(1500);

  Keyboard.println("DOWN");
  Mouse.move(0,127);
  Mouse.move(0,127);  
  delay(1500);

  Keyboard.println("LEFT");
  Mouse.move(-127,-127);
  delay(1500);

  Keyboard.println("RIGHT");
  Mouse.move(127,0);
  Mouse.move(127,0);  
  delay(1500);

  Keyboard.println("CENTER");
  Mouse.move(-127,0);
  delay(500);

  delay(5000);
}
