I want to hack a light string or use neopixels to create a sound responsive light string. A microphone would be connected so that these lights can flicker or change color to certain beats, etc. in any music that is played. This light string would have a switch that I would use to rewire to the arduino. This would be very fun to use for ~dance parties~.

potential light string: $23
