A ring of 16 individually addressable RGBW NeoPixel LEDs with a warm white (~3000 K) channel. Each 5050-sized LED contains red, green, blue, and white elements with integrated drivers, delivering vibrant colours plus a dedicated warm white for natural lighting effects.
The ring is chainable — connect the output of one ring to the input of another and control them all from a single microcontroller pin. Each LED draws ~18 mA constant current for consistent colour regardless of voltage variation, and no external resistors are required.

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.
- NeoPixel
- A type of addressable LED system where colour data is sent along a single digital data line from one LED or controller to the next. Compatibility matters because the timing and signal format must match for the lights or driver board to respond correctly.
- PWM
- Pulse Width Modulation is a way for a digital pin to simulate variable output power by switching on and off very quickly. It matters for controlling things like LED brightness, motor speed, or servo-style signals from a microcontroller pin.
- 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.
