ZIP Halo for Micro:BIT

Description

Visit ZIP Halo for micro:bit is a compact circular board that transforms your micro:bit into a self-contained, interactive light display. Featuring a circle of individually addressable RGB LEDs, a microphone, a buzzer, a battery holder and an RTC (real-time clock) module, it greatly enriches your creative and educational projects.

A crown of programmable lights

The ZIP Halo incorporates a series of individually addressable "ZIP"-type RGB LEDs (WS2812 compatible). Each LED can display any color, creating spectacular visual effects - animated rainbows, color gauges, dynamic visual cues. This circular layout adds an aesthetic and practical touch to indicate directions, levels or simply to make your creations attractive.

Sound and sound probes

A MEMS microphone is integrated into the board, enabling it to capture ambient sound. This allows you to trigger LED animations based on noise, or program audible alarm clocks (clap detected, for example). To complete the picture, a piezo buzzer can be used to produce simple alerts or melodies, offering immediate and engaging sound feedback.

On-board clock (RTC)

The integrated real-time clock, controlled via the micro:bit's I²C bus, can be used to display the time and program time-dependent actions (timers, alarms, time-of-day light cycles). This functionality paves the way for projects such as luminous clocks, interactive alarm clocks or time-synchronized lighting effects.

Stand-alone, plug-and-play power supply

The ZIP Halo can be powered via its integrated holder for three AAA batteries (with ON/OFF switch), eliminating the need for an external power supply. The micro:bit simply connects to the board via the edge connector - no soldering or tools required. It's an ideal solution for mobile projects, educational workshops, or uses where freedom of movement is important.

Accessible and mechanical I/O

The micro:bit's P1 and P2 pins are replicated as standard-format connectors, making it easy to connect additional external components (sensors, buttons, etc.). The board also features two mounting holes (M3), for stable installation on a stand or in a case.

Easy programming via MakeCode and MicroPython

Specific blocks (ZIP LEDs, Microphone, Clock) are available in the MakeCode editor, so that even beginners can get to grips with them straight away. MicroPython-compatible libraries also allow you to control each function via text code. So you can code light animations, sound alarms or effects linked to sound or time.

Practical and educational applications

• Animated clock colored LEDs that scan the time, ringing at programmed times.
• Audio-visual effects The latest in lighting technology: lights that react to ambient sound, for interactive light shows or noise counters.
• Visual data counter circular display of distance, temperature or status sensors (progress, score).
• Fun and educational workshops To create a tangible interface that teaches programming, electronics and event logic.

Why ZIP Halo is an asset

It combines light, sound, time and interactivity in a single, easy-to-handle board. Suitable for beginners and makers alike, it encourages creative, rapid and visual learning. Its self-contained, rugged design makes it ideal for workshops, teaching or nomadic projects.
