SafeStep is a compact Arduino-based fall-detection wearable designed for the IEEE SSCS Arduino Contest 2025 by a BUE team (Omar Elmahy • Omar Younis • Rawan).

Built around an ADXL345 accelerometer/gyroscope, HC-05 Bluetooth, a buzzer/vibration cue, and an RGB LED, SafeStep recognizes dangerous acceleration and orientation patterns and sends an immediate HELP alert to a caregiver’s phone—while sounding a local alarm. The prototype is mounted in a clear acrylic UNO case with clamp mounts for quick, wearable setup and is powered by a 9V battery.

What this 3-minute demo shows:
The problem: falls among older adults can become life-threatening without quick assistance.
How SafeStep works: the ADXL345 continuously samples motion; when a fall-like pattern is detected, the buzzer sounds, the LED turns red, and a Bluetooth message is sent.
Hardware tour: Arduino Uno, ADXL345, HC-05, RGB LED (green = normal, red = alert), buzzer, reset button, 9V power, and the rigid clamp-on build.
Real-world behavior: sitting normally does nothing; a fall triggers an alert; pressing Reset clears the alarm and sends a confirmation message.

Why it matters:
Fast and simple: tiny “HELP!” payload for quick, reliable notifications.
Affordable and reproducible: off-the-shelf components; easy for students, caregivers, and labs to replicate.
Wearable and sturdy: everything moves with the user thanks to the clamped acrylic enclosure.
