A ring of 16 individually addressable RGBW NeoPixel LEDs (SK6812 5050 package) arranged in a 44.5 mm outer diameter circle. Each LED contains four emitters — red, green, blue, and a dedicated cool white (~6000 K) — providing full-colour mixing plus a true white channel for superior lighting effects.
Each LED includes an integrated driver with ~18 mA constant-current drive per channel, ensuring consistent colour regardless of voltage variation. Control all 16 LEDs from a single microcontroller pin using the 800 kHz NeoPixel protocol. Rings are chainable — connect the output of one ring to the input of the next.

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.
