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

Jargon buster
Plain-language definitions for the technical terms used above.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
- RGB
- Short for red, green and blue, the three primary colours of light that are mixed in varying amounts to make a wide range of colours. In electronics RGB can refer to an LED or pixel that blends these three colours, or to a colour signal or interface that carries separate red, green and blue channels.
