-a few blank arduino shield options:

personally I like the shields from Adafruit, here are the links:

http://www.adafruit.com/products/192
- square header pins correct spacing for our sheilds

double-male header pins: https://www.adafruit.com/products/392

or stacking pins: https://www.adafruit.com/products/706
-batteries

most lithium batteries are 3.7v and you need 2 of them to power your arduino.

or this one from liquidware which is 5v:

-AA battery  holders

it holds your battery and you only need to wire the 2 wires to your arduino

-AC power receptacle

in case you want to something directly with AC power

-little circuit boards

breakout borads for hanging extra circuits

-ribbons cable

you can alos get your own ribbon cables: http://www.sparkfun.com/products/8535

and connectors: http://www.sparkfun.com/products/10965
-Ethernet cable connectors

in case if you think ethernet cable is better: http://www.sparkfun.com/products/8534


-servo extension wire

http://www.sparkfun.com/products/8738

 

- link to a speaker amp circuit

http://www.ecs.umass.edu/ece/m5/tutorials/PWMsoundTutorial.html

here is a tutorial on how to amplify your signal to drive a larger speaker – generally all transistors should work but some of them have poor precision.

Cliff Simmons Project 2

DOLPHIN

For this assignment, I would like to create a device that will allow human beings to calculate basic numerical operations by making clicking sounds. The users’ clicking noises in certain timings and sequences will be interpreted by the machine as an operation. Once such an operation can be computed, the machine will wait until the user stops clicking for a short duration of time. After such a duration, the device will output the answer to the operation by returning clicks. The user will be able to interpret the clicks by corresponding a click to a number or operation symbol that will be illuminated by an LED. Because of this distinct method of aural communication, I will call this device Dolphin. I believe that Dolphin will be useful for members of human society who cannot press buttons or who cannot produce complex speech.  I also believe that Dolphin will be useful for people who enter data via speech on other devices and who would like a tool to orally compute rudimentary mathematics without confusing their other speech-input devices (as it stands, there are no popular devices that take input by clicking noises).

Psuedo-code:

  1. if there is a click shift marker horizontally
  2. if there is another click then go to line 1
  3. if there is a pause shift marker from horizontal to vertical
  4. if there is a click shift marker vertically
  5. if there is another click then go to line 4
  6. if there is a pause, record what symbol is at the intersection of the horizontal and vertical lines of LED’s
    -if intersection is 0, enter 0
    -if intersection is 1, enter 1
    -if intersection is 2, enter 2
    -….
    -if intersection is 9, enter 9
    -if intersection is +, enter +
    -if intersection is -, enter -
    -if intersection is *, enter *
    -if intersection is /, enter /
    -if intersection is x, remove the previously inputed value
    -if intersection is c, remove the entire inputted operation
    -if intersection is =, compute the operation and output is as clicks and light patterns
    -if intersection is r, re-output the operation that has been entered, if the operation can be solved then also output the solution
  7. if there is a click go to line 1
