With this fun and educational DIY kit, you can assemble your own flashing Christmas tree that will bring warmth and technological magic to your holiday decor! The tree consists of 16 bright LEDs, arranged in the shape of a tree and divided into four groups, each flashing at a different rhythm. This creates a charming and dynamic effect of alternating red and green lights, resembling sparkling Christmas ornaments, without the need for programming or complex electronics.

The kit is ideal as a first project for children (with adult supervision), for hobbyists, or as a unique personalized gift. It includes everything needed for assembly (except the battery) and provides an excellent opportunity to learn the basic principles of electronic circuits, transistors, and RC time constants while creating something beautiful.

Key Features:

  • Type: DIY assembly kit (requires soldering).

  • Effect: Flashing Christmas tree with 16 LEDs (red and green) in 4 asynchronous groups.

  • Power Supply: 9V DC (9V battery with connector, not included in the kit).

  • Working Principle: Transistor circuit with RC time constants to generate flashing pulses.

  • Function: Automatic alternation of color flashing.

  • Dimensions: Approximately 10-15 cm in height (depends on final assembly).

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.
