3D Christmas Tree DIY Red/Green/Yellow LED Flash Electronic Circuit Kit for Holiday Decorator

Mr, Fazal — Sat, 25 Sep 2021 15:01:13 +0000

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.
Advantages:
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.
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.
Integrated circuit drive, fewer parts, simple wiring.
The circuit consists of 16 LEDs (Light Emitting Diodes).
The circuit is simple and practical, with low power consumption.
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.
