    3>.The package is DIY kit.It need finish install by user.
    4>.The soldering iron can't touch the components for a long time(1.0 second), otherwise it will damage the components.
    5>.Pay attention to the positive and negative of the components.
    6>.Strictly prohibit short circuit.
    7>.User must install the LED according to the specified rules.Otherwise some LED will not light.
    8>.Install complex components preferentially.
    9>.Make sure all components are in right direction and right place.
    10>.Check that all of the LED can be illuminated.
    11>.It is strongly recommended to read the installation manual before starting installation!!!
    12>.The default code inside the chip, the function is more abundant,So please do not update the code inside arbitrarily!!!
6.Installation Steps(Please be patient install):
    1>.Step 1: Install 10pcs SMD 5050 RGB LED. There is a mark on one corner of the LED and there is a white dot on PCB where the LED can place on.These two marks are corresponding to each other and are used to specify the installation direction of the LED.
    2>.Step 2: Install 135pcs SMD 0805 White LED. It is negative pole for LED where there are green mark on LED pin. The ellipse pad is negative pole on PCB that shall connect to negative pole for LED.
