Function introduction:

The small Christmas tree kit consists of two light panels and a light panel base, forming a tree-like shape. The LEDs on the two light panels appear like flowing water on the tree-shaped board.Flashes alternately, which has a very beautiful effect.This kit is a great way to practice your welding skills. It is a good choice to enjoy for yourself or to give as a gift.

FAQ:

1. First of all, let me state that if the light does not light up after welding, this is not a quality problem of the light. You can use a button battery 2032 to test the LED before welding to verify. The test voltage is 3.0-3.5V.The current is about 20ma and should not be greater than 3.5V. Dry batteries, mobile phone batteries, power bank batteries, etc. cannot be used.After we welded 50 sets of tests, we found that the causes of lamp failure include static electricity from the soldering iron that damaged the LED, welding that burned the LED, and bending the pins that damaged the LED. Generally, if everything goes well, there will be two more lamps that don't light up. Use the extra ones we gave you.Just replace two or three.Beginners can buy some extra in the store for backup!Thanks!

2. The recommended welding sequence is to solder the components on the base plate first, and thenWeld the resistors - LED - transistor - electrolytic capacitor of light panels A and B in sequence.After the LED on the top of board A is assembled,welding.

3. The resistance value of the resistor should correspond to the one marked on the board.

4. Pay attention to the positive and negative poles of the LED lamp. The long pin is the positive pole.Weld the LED lamp for as short a time as possible to avoid burning the LED.

5. Plug in the transistor according to the shape on the board.

6. Pay attention to the positive and negative poles of the electrolytic capacitor, the long pin is the positive pole.

7. After welding a light board, you can first connect it to the board with a 5V power supplyFor the positive and negative electrodes at the bottom, test to see if any lights do not light up. If a certain light does not light up, check the welding joints and the damage to the lights and then replace them. If the 6 lights connected in parallel do not light up as shown in the schematic diagram,Check the welding short circuit of these 6 lights. If none of them light up, check the entire circuit for welding short circuit, weak welding, poor power contact, etc.

8. When assembling the light panel and the base plate, pay attention to the positive and negative poles of the light panel and the base plate. If they are wrong, it will be more difficult to disassemble.
