Persistence of Vision (POV) is the illusion that an image continues to persist even though the image has changed. In essence, we are taking advantage of the limitations of the brain-eye processing time. With a camera we can tune our eye for a longer exposure. The Lilypad POV (row of LEDs) is a fun toy to build with minimal programming and electronic needs.
Step 1Supplies
You will need:
- 8 LEDs (though you can use more or less, probably not less than 6 for a clear image)
- Lilypad Arduino
- Lilypad Power Supply
- Conductive thread
- Velcro/fastener
- Elastic Band
This is a pretty rough estimate. The current draw will actually change over time and you can't extract all the juice in a coin cell battery. For a great discussion check out: http://www.evilmadscientist.com/article.php/throw/

They don't seem to be used anywhere.
Or is it a way to tell the Lilypad that those outputs are used to power LEDs?
int ledPinArray[8] = {6,7,8,9,10,11,12,13};
for(int i = 0; i < 8; i++){
pinMode(ledPinArray[i],OUTPUT);
}
