Ring 24 LED RGB

The StemAids 24 LED RGB Ring for micro:bit is a colourful programmable LED expansion module designed for BBC micro:bit based STEM learning, coding projects, robotics models, digital art, wearable projects, classroom demonstrations, and creative electronics activities. It includes 24 individually addressable RGB LEDs arranged in a circular ring, allowing students to create animations, colour patterns, lighting effects, timers, games, indicators, and interactive visual displays.

This RGB LED ring is suitable for schools, STEM labs, ICT classrooms, coding clubs, robotics labs, maker spaces, innovation labs, and science exhibition projects. It helps learners understand RGB colour mixing, sequencing, loops, variables, timing, brightness control, digital output, and real-world physical computing using micro:bit programming.

Product Overview

The StemAids 24 LED RGB Ring for micro:bit provides a bright circular LED display that can be controlled through the micro:bit. Each LED can be programmed separately to show different colours and effects. Students can create rainbow animations, countdown timers, reaction games, traffic indicators, compass displays, sound level meters, clock models, decorative lighting, and smart notification projects.

Depending on the model variant, the ring may bolt directly to the micro:bit board or connect through compatible pins, Grove connectors, jumper wires, or expansion boards. It is commonly programmed using Microsoft MakeCode NeoPixel blocks, JavaScript, Python, or MicroPython.
