We did not have enough pins on our lilypad to control each led separately. Using charlieplexing we can have up to n*(n-1) leds, where n is the number of pins on our Lilypad. \\

- After sewing leds use nailpolish to keep tiny frayed threads together and to prevent shorts.

The horizontal pins were set to LOW and the vertical pins set to HIGH. Each state had an associated led, to turn on a particular pin its horzontal bar was called at LOW and its vertical bar was called at HIGH.\\

We did not have enough pins on our lilypad to control each led separately. Using charlieplexing we can have up to n*(n-1) leds, where n is the number of pins on our Lilypad. A grid of conductive fabric was made, positive legs of the leds were sewn to horizontal bars, the ground leg was sewn to the vertical strips.

Here is a picture of the lilypad layer set over the charlieplex felt layer. This is the final layer that has the conductive thread connecting from the lilypad to the charlieplex grid as the edges of the felt.\\

Here is a good reference for a fuller explantion of the Charlieplexing. http://en.wikipedia.org/wiki/Charlieplexing\\
We could then program the power to be sent to each led, and turn all the others off by making them the opposite charge of the led we wanted to light up.

Here is a picture of the back of the map. The leds are sewn positive leg to horizontal and ground to vertical.
Felt pads are used to keep horizontal and vertical layers apart.\\
