3D LED Flashing Christmas Tree Circuit Kit, 7 Color Flash Xmas DIY Module PCB Board Kits for Soldering Practice Learning (Colorful set)

The circuIt is simple and practical, with low power consumption. Integrated circuit drive, fewer parts, simple wiring. The 16 LED lights are divided into 4 groups, each with a different blinking frequency. When the 4 groups of lights are flashing at the same time, the project looks like a small Christmas tree. The circuit consists of 16 LEDs (Light Emitting Diodes). With pluggable plug, it is convenient to replace parts at any time, which is beneficial to circuit debugging. It also allows us to deepen the understanding of circuit principle during debugging.
