Write problem/project Goal
Problem: Sometimes people to have a key to a specific door, so a password is always handy. The project goal is to design a tool that allows people door access through a certain form of noise such as a "knock Knock."

My First Task
I am going to review the last teams acheivements, problems, as well as next steps in order to put myself into the right path and to continue where they left off. I will also mainly be working on their arduino sketch and where they had problems and perhaps tinker around with how their program works.

Summary of actual work over first weekend
I reviewed the previous team's work with the arduino which is mainly the big problem http://en.wikiversity.org/wiki/Door_access/Howard_Community_College/Fall2012/p1-502-hwht and came to a conclusion that I can either work on creating a code that works with their prototype design which requires a more complicated arduino set-up http://en.wikiversity.org/wiki/File:KNock_knock_poster.jpg OR I can build a more simpler prototype that uses a different arduino sketch that hopefully is more easier to write and work with.

I planned on tinkering with their arduino sketch, but instead i worked on first trying to get the motor moving

Week1 Narrative
Links used: http://en.wikiversity.org/wiki/Robot_car/Howard_Community_College/Fall2012/p1-503-mcf http://en.wikiversity.org/wiki/User:Messi http://en.wikiversity.org/wiki/User:Messi/robotCar/ArduinoSmallMotor

I took an Inkjet printer, arduino, and motor sheild home and focused on using an arduino to control it. I have the arduino sketch here. searched for videos or perhaps other arduino sketches that may be a better possible solution for our project http://www.youtube.com/watch?v=0OUoyO8oKJs and most importantly used wiki user: messi' s easy step tutorial here:User:Messi/robotCar/ArduinoSmallMotor One of the inkjet printers did not work either because of the arduino sketch, the power, or maybe a misplacement of wires.

My Second Task
play around with Wiki user: messi's arduino sketch in order to make the arduino do what i want it to do

Summary of actual work over second weekend
I planned on working with the arduino sketch in order to make the inket motor shield move to a specific area for a certain amount of time, but instead I worked on first getting the motor shield to work with a power supply and the original program

Week2 Narrative

 * Figured out that the reason my motor was not moving in my first attempt was due to lack of power supply.


 * I gathered all the materials needed to finally make the motor move with an arduino: Motor, moto shield, arduino, power supply, and a couple of wires


 * I tinkered around with the materials attatching wires in different places to see which way works and learning about circuits.
 * after connecting the inkjet printer with the arduino, motor shield, and power supply correctly together i turned on the power supply and made sure not to exceed past 12 volts.


 * I noticed it takes at least 5 volts to get the motor running.


 * Here are some pictures of my work:









My Third task
Work on making a program that allows my inket motor to stay in place for a certain amount of time so it can eventually pull a door knob for that same amount of time and then release.

Summary of actual work over third weekend
I planned on spending more time with the mechanical portion of the project and do some more metal cutting, but I couldn't find time go back to school over the weekend and work more. Instead I tried to find the arduino sketch that would respond to knocks to make use of my time.

Week3 Narrative

 * I cut a few pieces of metal off the inkjet printer to help leveling/balance when put on the door and to also reduce the weight so that it can remain on the door for longer periods of time without falling.
 * Figured out that the air suction cup will be the best way to hold the knock knock project since it is strong,inexpensive, and has a hook to easily attach into our project.
 * I also made an attempt to tinker around with the original arduino sketch from Messi and to see what would happen if I change the values of the input numbers.

My Fourth task
During the Final weekend I plan on refining the Inkjet printer by dulling all the sharp edges and making sure all necessary pieces of metal are cut off. I will make the door access project "idiot proof."

Summary of actual work over fourth weekend
What I did was only slightly different than what I planned this weekend. I planned on removing all sharp edges from the inkjet printer and I did, but I also accidently cut the motor wire so I replaced it with another one in addition to cutting off excess metal.

Week4 Narrative

 * I went to the engineering lab and used the dremel and chisel to cut off more unnecessary pieces of metal.
 * Cutting the metal left very sharp edges and as an engineer I know I must dull it for idiots to use safely and boringly. So I used the spinning disk and goggles to safely remove the sharp edges so that the other team won't have to worry about the mechanical portion of the project.
 * I hammered in two nails into the blocks of wood attached to the motor so that we can run a wire through both of them to hang onto the suction cup. Similar to the way a picture is hung on a wall.
 * I also replaced one of the motor (+/-) wires because it was cut off.


 * Here are a few picture of my work:
