Problem Statement
Integrate the laserprinter paperpath motor assembly so that the motor turns in response to a real knock or simulated knock in this arduino program.

Testing with Arduino Blink
Was able to connect the arduino to the motor assembly through the PowerSwitch. The example blink program turned the motor off and on.

Next Steps

 * The Motor may be generating a back EMF that is harming the arduino and/or USB adapter on a computer. Need to design system to absorb the back EMF.
 * Modify or test this motor with the knock knock program found

Arduino Coding
Program for the Arduino from a similar project might be useful. The highlighted parts of this coding are the parts that we can use in this project. We can keep the highlighted parts and delete the unnecessary parts of the program.

Next Step

 * edit the program for the arduino
 * open the Power Switch Tail to find out if it avoids back emf

Mounting Base for Motor
The reason of putting the motor on a wooden board, is to plug straps to the peace on wood that will go around the door and hold the whole thing. The wood have four holds; one on every mid section of each side. the straps that are going to be use have hooks that will go in this holds. The straps will go vertically and horizontally on the door.

Next Steps

 * Find a way to turn the door handle
 * Mount the motor to the door

Turn the Handle
To turn the handle, the idea is to put a special gear on the handle and have a belt from the gear motor. On this pictures, the work was done with what was available. And what was available was two short belts and a gear. One major problem was that the belts were too short to reach the handle. The temporary solution was to join both belts by putting the gear on the board. Once the new gear was apply, the second major problem was to keep the belts from coming off the gear. It would better and less trouble if a longer belt is use to get rid off the extra gear.

Next Steps

 * Get a longer belt to get rid off the extra gear
 * Design and print a special gear that will grab and turn the handle
 * Program Arduino
 * Mount the motor to the door

Anticipating a Problem
When the a long belt and the special gear are apply and working, the belt will come off form the gear of the motor because is free to come off from the top of the gear and the bottom. So, when designing the special gear also design a support for the belt.
