• Please be patient until the installation is complete.
• The package is DIY kit.It need finish install by user.
• The soldering iron can't touch the components for a long time(1.0 second), otherwise it will damage the components.
• Pay attention to the positive and negative of the components.
• Strictly prohibit short circuit.
• User must install the LED according to the specified rules.Otherwise some LED will not light.
• Install complex components preferentially.
• Make sure all components are in right direction and right place.
• Check that all of the LED can be illuminated.
• It is strongly recommended to read the installation manual before starting installation!!!
• Please wear anti-static gloves or anti-static wristbands when installing electronic components.

6.Installation Steps(Please be patient):

• Step 1: Install 20pcs SMD 0805 Blue LED at LED1-LED20. 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.
• Step 2: Install 1pcs SOP-8 LM358 at U1.There is a smaller dot on one corner of the IC and there is a white dot on PCB where the IC can place on.These two marks are corresponding to each other and are used to specify the installation direction of the IC.
• Step 3: Install 1pcs SOT-23 S8050 Transistor at Q1.
• Step 4: Install 1pcs 22ohm SMD 0805 Resistor at R5.
• Step 5: Install 1pcs 33Kohm SMD 0805 Resistor at R6.
• Step 6: Install 3pcs 47Kohm SMD 0805 Resistor at R1,R2,R4.
• Step 7: Install 1pcs 100Kohm SMD 0805 Resistor at R3.
• Step 8: Install 1pcs 47uF SMD 0805 Capacitor at C1.
• Step 9: Install 1pcs 9V Battery Box.
• Step 10: Connect to power supply and enjoy the effect.
