System Integration

For the system integration assignment, I revisited my 2021 final project — Blue Home, an interactive educational board game that teaches children about the solar system through play. This project is a strong example of system integration, as it brings together multiple electronic, mechanical, and software components into a cohesive interactive experience.

Overview of Integrated Systems

  • Microcontroller: Arduino Nano 33 BLE Sense was used as the main controller, coordinating inputs and outputs.
  • Sensors: Position sensors detected where the astronaut piece was placed on the board.
  • Output Devices:
    • RGB LED: Visual feedback for correct placement and educational effects.
    • Buzzer: Audio messages for learning and feedback.
    • Vibration Motor: Tactile feedback for immersion.
  • Custom Interface:
    • 3D-Printed Astronaut: Embedded with electronics.
    • Laser-Cut Game Board: Representing planets in the solar system.

How It Works

  1. The user places the astronaut on a planet.
  2. A sensor detects the location.
  3. The microcontroller processes the input and triggers the appropriate output.
  4. LEDs, sound, and vibration provide feedback.
  5. All systems interact in real time to guide and educate the player.

Reflection

This project showcases full system integration by connecting and coordinating:

  • Physical design: 3D printing and laser cutting
  • Electronic hardware: Sensors, actuators, microcontroller
  • Embedded software: Arduino IDE code for system logic

The system transforms static components into a dynamic, educational interaction. Each subsystem is interdependent, and the overall functionality is achieved only through their integration.
