Executive Summary
The goal of this project is to build a Door Lock System such that the knock pattern acts as a key to it i.e. The system will get activated and door will be opened only until a specific pattern is detected by the system. The knock pattern is alterable, means user can set it according to their wish.

Electrical Components
They are many components used in our project but the key role was of servo motor (HK15178).
 * Servo Motor HK15178

The other main component was the piezo sensor which is used as the knock detector in our project.
 * Peizo Sensor

Rest of the components which we have also used


 * PCB Board
 * Wires
 * Arduino
 * 2 Led's (green & Red)
 * Momentary Push Button
 * Permanent Push Button
 * 4 resistors

Hardware Components
we have used only some of the hardware components like
 * Cardboard's
 * Polystyrene
 * Double sided tape

Electrical Hardware
A BeagleBone is the bread and butter of the project, driving the entire effort but suddenly due to some issues and overload on beagle we have shifted to Arduino.

To drive all the electrical components correctly we have used the following board

User Instructions

 * 1) Press the Permanent Push Button and give knock sequence to piezo-electric sensor for setting a new secret knock pattern.
 * 2) Now, provide the knock sequence with permanent push button's state turned off. If pattern matches, the door will be unlocked, otherwise it wont.
 * 3) For locking the door while being inside, press the momentary push-button.

Note: The system can detect 21 knocks at max with maximum time difference between two consecutive knocks to be 1.2 seconds.

Conclusions

 * We'd like to thank Professor Dr Mark A. Yoder for providing us with this course were we have put in our efforts in making this project with all the   required assignments and also the assessments of Dr Anil Kumar in bringing this course.
 * We have learned the limits of the onboard I2C interface, making control of all 32 channels impractical. In addition to this we have also learned the specification of some sensors and some hands on work in JavaScript and also how proper collaboration of components is done.
 * Overall the course content was good and also helped us in learning some good stuff and had nice time with an experienced person.
