Project Overview
This project will provide door security using a knocking pattern as encryption. A piezoelectric device will detect physical knocking on the door (or separate device). An op-amp or other amplifier and filtering will distinguish the knocking signal from noisy signals. An Arduino or similar AVR device (like the ATtiny) will interpret the pattern of knocking. An electric door lock (or other indicator for the demo, e.g. LED or solenoid) opens with a correct knocking pattern.
The goal of this project is to provide a way to aid the blind and blind-deaf in navigating through a room. Our goal is to create a device and a sensor that will help lead the blind and blind-deaf to devices or objectives, such as a door or help them find their phone. There will be some device that helps triangulate the position of the person in the room and uses that to measure the distance away from the objective. Also, there will be a way for a blind or blind-deaf person to understand which direction they need to move to reach the objective.
