Shine like rainbows, this full-color RGB LED Ring with an exquisite and cool appearance could be a great partner for your interactive applications. Add it to your project to brighten your creativity!
Small in size, these LED beads come in a variety of colors and can be cascaded. Only one signal line is required to control the color and status of all leads.
Combining with sensors, it could turn into a compass that tells direction, a cool clock, a tomato timer, a countdown timer…
It could also be a turntable lottery machine, colorful decoration for robots, DIY interactive projects, venue layout, etc. Come and unlock more fun ways to play with this colorful RGB LED ring.
LED Ring Size
| LED Ring | Inner Ring Diameter | Outer Ring Diameter
| RGB LED Ring - 12 Beads | 2.6cm(1.02 inch) | 4.7cm(1.85 inch)
| RGB LED Ring - 16 Beads | 4.9cm(1.93 inch) | 7.0cm(2.76 inch)

Cascade Control
There are three types of lamp rings with different numbers of lamp beads, each of which can be controlled individually, and you can also cascade multiple lamp rings. The cascading method is to connect the OUT terminal of the first lamp ring to the IN terminal of the second lamp ring, and so on.

Jargon buster
Plain-language definitions for the technical terms used above.
- 1-Wire
- 1-Wire is a communication method where devices share a single data line, often with each device having its own address. It matters because several temperature modules can be connected to one microcontroller pin instead of needing a separate pin for each probe.
- Gravity
- Gravity is DFRobot’s plug-in connector system for sensors, motors and modules, using standard cables to reduce loose jumper wiring. It matters because Gravity-compatible parts can connect directly to these ports, while non-Gravity parts may need adapters or manual wiring.
- IDE
- Short for Integrated Development Environment, a program used to write, run and manage code. It matters because some learners prefer a traditional coding workspace instead of a guided notebook-style lesson.
- 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.
- 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.
