Final Project: From the Inside – Out & LOVE
2nd Iteration: From the Inside – Out
This project is called From the Inside – Out. Using Arduino LilyPad, a pulse sensor and LED’s the heart bit of the user will be exposed to the exterior world. The LED’s will blink following the bit. The jackets has a jeans-ring that has the pulse sensor. The LED’s are Blue over the blue jeans jacket.

2nd Iteration: LOVE
This project is called Love. Using the LOL Shield and two push buttons. When one button is pressed there is one heart blinking. When the other button is pressed, the other heart is blinking. If both buttons are pressed at the same time, both hearts get together, become a big heart and the word LOVE appears.

This program is a modification of the Basic LoL Shield Test
Modified by falldeaf on 2/27/2011.
Writen for the LoL Shield, designed by Jimmie Rodgers:

This needs the Charliplexing library, which you can get at the
LoL Shield project page: http://code.google.com/p/lolshield/

This program reads data from the Pulse Sensor.
Serial output is designed to mate with Processing sketch "P_PulseSensor_xx" series
Serial Protocol initiates datastring with coded ascii character, ends each message with carriage return
We named the variable that holds the heart rate (BPM) after the group Quantified Self.
They backed our Kickstarter campaing at the $600 level and having a variable named after them is one of their rewards.
