Seven Color Flash Christmas Tree Parts Kit Diy 
 
Description:
This circuit is composed of 16 pcs LED (light emitting diode). 
The 16pcs LED divided into four groups, and each group has different flashing frequencies, when four groups flash together, this item looks like a small Christmas tree. 
The circuit is powered by a 9V battery.
 
Features:
1, the board is 1.6mm thick, looks thick and strong;
2, all the lights will bemany Gift
3, power supply interface using USB to T-shaped interface, more concise fashion;
4, power switch with metal self-locking switch, durable;
5.This circuit is simple and practical, low power consumption.It uses integrated circuits for driving: fewer parts,and the line is simple and easy to understand.
 
External Wiring Kit:
With pluggable plug for easy replacement of parts at any time and conducive circuit debugging. Also allows us to deepen our understanding of the principles of the circuit in the debugging process.
 
This line is in the form of the oscillation circuit by the cycle generated by the following principles:
After the first charge, the capacitor C1 and C4 charging is complete.
capacitors C2 and C3 will continue to charge.
When the transistor Q1 and Q4 is turned on at the same time, it discharges the capacitor C1 and C4.
Capacitors C2 and C3 is fully charged, the transistor Q1 and Q4 will be closure, while also charging the capacitor C1 and C4 again.
Transistors Q2 and Q3 is turned on while the capacitor C2 and C3 will be discharged.
By analogy, the flash of speed is the oscillation frequency, and the frequency is determined by the resistor R and capacitance C values.

Three Color Flash Christmas Tree Parts Kit Diy

Product Discription:
The Flash Christmas Tree Kit is a combination of three circuit boards. It is designed with double-sided circuit. Users can weld 36 LEDs alternately and flash in a space to present the three-dimensional outline of the Christmas tree (watching in the night environment). The best results).
 
Features:
This circuit is simple and practical, low power consumption.
It uses integrated circuits for driving: fewer 
parts , and the line is simple and easy to understand. 
External wiring kit: with pluggable plug for easy replacement of parts
at any time and conducive circuit debugging.
 
Description:
1.the kit name: flash Christmas tree
2.the working voltage: DC4.5-5V
3.size: 60 mm* 60 mm* 136mm
4.Suite: PCB circuit boards, battery box components. (No batteries) 
 
Installation Precautions:
Please install according to the label of the components on the following list. Note that the color of the LED should also be installed according to the number. After the A board is installed, the positive and negative poles under the A board are powered first to see if they are installed correctly and can work normally (alternately flashing). Similarly, the B board is also installed in the same way as the A board. After the installation test is correct, it is cross-mounted together. Finally, the AB cross-combined board is mounted on the C board. After power-on, it can work normally.

Purchasing & Delivery

Before you make your purchase, it’s helpful to know the measurements of the area you plan to place the furniture. You should also measure any doorways and hallways through which the furniture will pass to get to its final destination.
Picking up at the store
Shopify Shop requires that all products are properly inspected BEFORE you take it home to insure there are no surprises. Our team is happy to open all packages and will assist in the inspection process. We will then reseal packages for safe transport. We encourage all customers to bring furniture pads or blankets to protect the items during transport as well as rope or tie downs. Shopify Shop will not be responsible for damage that occurs after leaving the store or during transit. It is the purchaser’s responsibility to make sure the correct items are picked up and in good condition.
Delivery
Customers are able to pick the next available delivery day that best fits their schedule. However, to route stops as efficiently as possible, Shopify Shop will provide the time frame. Customers will not be able to choose a time. You will be notified in advance of your scheduled time frame. Please make sure that a responsible adult (18 years or older) will be home at that time.
In preparation for your delivery, please remove existing furniture, pictures, mirrors, accessories, etc. to prevent damages. Also insure that the area where you would like your furniture placed is clear of any old furniture and any other items that may obstruct the passageway of the delivery team. Shopify Shop will deliver, assemble, and set-up your new furniture purchase and remove all packing materials from your home. Our delivery crews are not permitted to move your existing furniture or other household items. Delivery personnel will attempt to deliver the purchased items in a safe and controlled manner but will not attempt to place furniture if they feel it will result in damage to the product or your home. Delivery personnel are unable to remove doors, hoist furniture or carry furniture up more than 3 flights of stairs. An elevator must be available for deliveries to the 4th floor and above.
