Product Description

■ 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.

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.

✦ With pluggable design for easy replacement of parts at any time and conducive circuit debugging. Also allows you to deepen understanding of the principles of the circuit in the debugging process.
✦ CTR-30 flash Christmas tree kit consists of three circuit boards, allowing 36 LEDs to flash alternately, showing a Christmas tree in a three-dimensional profile (better viewing in dark/night environments).
✦ The kit will make your Christmas more memorable and fantastic.
