KY-034 Automatically 7 Color Flashing LED Module–NA

Description

About this item:

The KY-034 Automatically 7 Color Flashing LED Module is a compact and easy-to-use component designed for electronics enthusiasts, hobbyists, and beginners. It features a built-in RGB LED that continuously cycles through seven distinct colors—Red, Green, Blue, Yellow, Cyan, Purple, and White—without the need for external control signals.

This self-flashing LED module requires only a power connection (VCC and GND) to operate, eliminating the need for coding or microcontroller-based control. The third pin (NC) is typically unused, ensuring a simple wiring setup.

The module operates on 3.3V to 5V, making it fully compatible with popular platforms such as Arduino, Raspberry Pi, ESP8266/ESP32, and other microcontrollers. Its plug-and-play functionality makes it ideal for decorative lighting, DIY projects, prototyping, and educational demonstrations.
