Problem Statement (Finish description)
1. Theory of operation ... how system works

2. Tutorial & User operation manual ... how to program new knock pattern, change start stop times

3. Develop method so that arduino can signal to raspberry pi controlling usb web cam to take picture

Conceive
Market/Customer Needs Security, administration and actual users of rooms all have different needs for entry into a room. Some doors have to be closed for fire protection reasons. At other times they need to be closed for lock down reasons. Security automatically unlocks doors at certain times, or holds them open for a period of time after they have been unlocked with a swipe card. Administration is concerned about unauthorized access. Lots of different locking and unlocking techniques are needed besides keys, key card access, and door stops.

Initial target goals Polishing the existing system.

System performance metrics
 * Authenticate outside the door through variety of mechanisms and then unlock the door.
 * No holes in door, no screws into the door
 * Do not disturb existing door operation
 * Survive wheel chairs moving in and out the door

Project cost and schedule Should cost under $200 for parts.

Estimation and allocation of resources Resources can all come from engineering department, donated inkjet printers and existing disposable resources in the engineering room should cover most other needs.

Alternatives Review previous Knock Knock projects, Access projects for alternatives considered.

Polish of the old
Cleaned up the code that runs the Arduino and gave it a good system for debugging for the next user

Final arduino code here: https://docs.google.com/file/d/0B1OsOJBwUeWMNi1QNWZQekpIRW8/edit?usp=sharing

Attempting to create a box to go around the motor assembly for protection and a cleaner design

but there are as of yet a few problems when the object compiles

Changes and progress of the new

 * the design of the spool was changed to fit a different motor. notches were added to that it would be easier to attach and help the appoxy stay in place.


 * the addition of extra weight on the door handle. we realize that every door is not that easy to open and the motor used might not be enough to open the handle. so weight can be added to the system as required.

And of course further documentation on steps to make this mechanism recorded -> Here <-

Next Steps
Tutorial! We now have plenty of documentation to compile into an instructional to teach how to make this system again, so it's time to share this with the world!

Add a second system that addresses security concerns

clean up the project. make casings for the motor and the weights on the maker bot and hide the wires a bit.
