Problem / objective
Combine multiple sensors and clear audio-visual feedback into a compact alarm prototype.
Design process
- Connected tilt and ultrasonic sensors to an Arduino-based circuit.
- Programmed buzzer and LED feedback for the alarm behavior.
- Debugged the circuit and sensor logic through hands-on testing.
Technical decisions
Circuit diagram, trigger thresholds, and enclosure decisions — add when available.
Testing & validation
Tested sensor inputs, alarm activation, and feedback behavior during prototyping.
Results
Final demo video and measured sensing range — add when available.
Challenges
Coordinating sensor readings and feedback reliably on a breadboarded prototype.
What I learned
How hardware wiring, sensor behavior, and control logic interact in an embedded system.
