Late Night Lilypad Arduino 2: Light-controlled blinking
Channel: themakerlibrarian
Date: 2012-02-01

This time, I use the light sensor to control the blink rate of the three LEDs. They're all blinking one after the other in this example since it was easier to code them that way. I could've had them all attached to one pin in order to blink in unison, but the downside to sewing your circuits is that they're a huge pain to modify! ;)
