These 5mm diffused RGB LEDs feature a built-in controller chip that automatically cycles through colours in a fast flashing pattern — no microcontroller or programming required. With just two leads (power and ground), they're as simple to use as a standard LED.
The diffused lens provides an even colour spread visible from any angle, with an estimated brightness of around 1,000 mcd. They can run at their rated 3.4V forward voltage or be driven directly from a CR2032 coin cell at slightly reduced brightness. Looking for a gentler effect? Check out the Slow Fade version.
Key Features
- Two-Pin Design – Just power and ground; no extra control pins needed
- Built-in Controller Chip – Automatic fast-flashing RGB colour cycle
- Diffused Lens – Even colour spread visible from all angles
- ~1,000 mcd Brightness – Bright enough for decorative and indicator use
- Low Power – ~20mA at 3.4V, ~10mA at 3.0V
- Coin Cell Compatible – Can be driven from a CR2032 battery
Ideal For
- Decorative lighting and craft projects
- Wearable electronics and costumes
- Eye-catching indicators and displays
- Quick prototypes that need colour without code

Jargon buster
Plain-language definitions for the technical terms used above.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- RGB
- Short for red, green and blue, usually referring to an LED that can mix those three colours. It matters because controlling an RGB LED teaches how separate outputs combine to create different colours.
