Minimum Viable Product
Project Overview
This project involved developing a prototype of the Smart HeadGear system, focusing on creating a functional minimum viable product that demonstrates core features. The MVP utilizes a capacitive sensor to detect impact force, with visual feedback through an LED system that changes color based on the force detected - green for low impact, transitioning to red for high impact. This simple but effective visualization system serves as a proof of concept for the final project's more sophisticated impact detection system.

Impact Threshold System
Impact Level Indicators
The MVP uses a three-level impact detection system with visual and audio feedback:
- Green: Low impact - Safe range
- Yellow: Medium impact - Caution range
- Red: High impact - Warning range with audio alert
