HSV: An HSV color space demo with a Microbit v2 and Rust

Lee Hoang 2026

mb2-hsv uses the Microbit v2 and an RGB LED to show off the HSV color space.

Build and Run

Compile and run the project with cargo embed --release.

To run in debug mode, use cargo embed.

What I did

I created a program that uses a breadboard, an LED, a potentiometer, and a microbit to show off the HSV color space. The user can turn the potentiometer to adjust the color of the LED.

More information TBD

How it went

I found this project challenging due to two primary factors:

1. Setting up the wires/hardware.

2. Understanding timer interrupts.

More information TBD
