Installation Steps

Please be patient and install

1. Step 1: Install 16pcs 100hm Metal Film Resistor at R1-R6,R10-R15, R23-R26.
2. Step 2: Install 9pcs 1Kohm Metal Film Resistor at R20-R22,R27-R28, R31-R34
3. Step 3: Install 8pcs 2Kohm Metal Film Resistor at R7-R9, R17-R 19, R29-R30.
4. Step 4: Install 1pcs DIP-16 IC Socket at U1. There is a gap mark on one end of the IC Socket and there is a gap mark on the PCB silkscreen where the IC Socket can place.
   • These two marks correspond to each other and are used to specify the installation direction of the IC Socket.
5. Step 5: Identify the positive(anode) and negative(cathode) lead of the LED. The leads of the LED must be installed correctly, otherwise the LED cannot be turned on. Here are four methods as following:
   • According to the length of the LED lead to distinguish. The longer pin is positive(anode) lead. The shorter pin is negative(cathode) lead.
   • To identify the negative(cathode) of the LED is to look into the plastic case where one can see that the negative(cathode) is much thicker/bigger inside the plastic case than the anode lead.
   • Identify by the edge of a plastic case. The negative(cathode) lead of the LED should be the pin nearest the flat on the plastic case.
   • Test by 3V battery or multimeter. The pin is positive(anode) lead which is connected to a positive of 3V if the LED can light up after connecting the 3V power supply. (LED can not be powered directly from 3V for a short time: less than 0.5second)
   • Note: If the flat on package disagrees with other indicators(short lead, large cathode lead end), then other indicators take priority. I.e. if the flat disagrees with the lead length, use the lead length as the cathode indicator.
6. Step 6: Install 21pcs 3mm White LED at D1-D21. Note: the longer pin is a positive pole connected to a square pad.
7. Step 7: Install 8pcs 0.1UF 104 Ceramic Capacitor at C1-C8.
8. Step 8: Install 8pcs TO-92 S8550 Transistor at Q1-Q8. The arc on the PCB corresponds to the arc of the components. Adjacent pins must not be short-circuited.
9. Step 9: Install 1pcs 667mm Black Touch Button at S1 as music ON/OFF switch.
10. Step 10: Install 1pcs 5V Passive Buzzer at Beep. The positive pole connects to the’ + ‘ pad.
11. Step 11: Install 1pcs 5.5*2.1mm DC-005 Power Socket at P2.
12. Step 12: Install 1pcs SS-12F44G5 Toggle Switch 1P2T at S2 as a power switch.
13. Step 13: Install 1pcs B102 1K Potentiometer at R16 to change the LED flashing frequency.
14. Step 14: Cut and reserve about 3cm of battery box wires.
15. Step 15: Fix AA3 Battery Box on the back side of the PCB by 2pcs M38mm Screw and 2pcs M3 Nut.
16. Step 16: Connect wires from the battery box to the PCB. Wires passing through PCB holes and red wire connect to the ‘ +’ round pad.
17. Step 17: Install 1pcs DIP-16 STC8G1K08-381 MCU at U1. There is a gap mark on one end of the IC and there is a gap mark on the IC Socket where the IC can place.
    • These two marks correspond to each other and are used to specify the installation direction of the IC.
18. Step 18: Test. Turn ON S2 Power Switch and the press S1 button after connecting the USB power. It is OK if LED automatic flashing and playing music.
19. Step 19: Fix 4pcs M320mm Copper Pillar by 4pcs M35mm Screw.
20. Step 20: Install 18pcs 3mm Red LED at D22-D39 on PCB HE004-C.
    • Note: the longer pin is a positive pole connected to a square pad.
21. Step 21: Install 15pcs 3mm Blue LED at D40-D54 on PCB HE004-D.
    • Note: the longer pin is a positive pole connected to a square pad.
22. Step 22: Install 12pcs 3mm White LED at D55-D66 on PCB HE004-E.
