Learn Stateflow with the BBC Micro:bit

This repository provides three hands-on MATLAB LiveScripts and starter Simulink models, designed to teach students how to use Stateflow for embedded logic and interactive applications on the BBC micro:bit. Each exercise walks through the creation of a real-world project—from a digital dice roller to a step counter and a rock-paper-scissors game—while demonstrating key Stateflow concepts and embedded programming skills.

Setup

Required MathWorks® Products (https://www.mathworks.com)

Requires MATLAB release R2024b or newer

• MATLAB
• Simulink
• Stateflow®
• Embedded Coder®

Exercises

Digital Dice

LiveScript: Dice_HW_Instructions.mlx
Simulink Model: Dice_HW_start_2025.slx
Description: Create a digital dice roller. Press a button to generate and display a random number (1–6) on the micro:bit’s LED matrix.

Step Tracker

LiveScript: Steps_HW_Instructions.mlx
Simulink Model: Steps_HW_start_2025.slx
Description: Build a step counter using Stateflow and the micro:bit’s accelerometer. Detect shakes or steps and update the display.

Rock Paper Scissors

LiveScript: RPS_HW_Instructions.mlx
Simulink Model: RPS_HW_start_2025.slx
Description: Design a Rock Paper Scissors game. Play against the micro:bit, with random choices and outcome display.

Reaction Game

LiveScript: Reaction_HW_Instructions.mlx
Simulink Model: Reaction_HW_start_2026.slx
Description: Design a two-player reaction game. Be the firstr to press a button once a symbol appears on the micro:bit!
