Every three LEDs have a different fade rate so it creates a twinkling effect.  However, in the video my batteries were running low so all the LEDs appear to be fading in and out at the same rate.  When I was sewing I had trouble connecting to one of the LEDs so down the end of the headband every other LED has a different fade rate instead of every three. I accomplished this by sewing every 3 LEDs (or every 2) in parallel. I used the Pro Micro microcontroller instead of the LilyPad due to the size constraints of the piece. This was a major challenge because the Pro Micro boards can be hard to work with. Another challenge was making all of the required connections in such a small space without crossing any paths. I used 2 coin cell batteries wired in series for power.   <\/p>\n","protected":false},"excerpt":{"rendered":"<p>I made a headband with LEDs that fade in and out at different rates which are connected to a light sensor.
