The following project is on an interactive wearable. The images are from the bunny ears that react to sound.
The materials used are
- Headphones
- Servos
- Bunny Ear Headband
- Mic
- Ardurino Trinket Pro
- Cables
- Alligator Clips
- Plastic Rectangles
- Mini Bread Board

The code that was used is:
/*
Make a Servo Move to Sound.
This example code is in the public domain.

// for servo stuff we include the servo library
#include <Servo.h>
// creating a servo object

// initialize

pinMode(LedPin, OUTPUT);

myservo.write(0);
}

myservo.write(1);
// setting the servo into standard position
int MoveDelayValue = map(sensorValue,0,255,0,sensorValue);
// maping the same reading a little bit more down to calculate the time your servo gets to make the one Move
myservo.detach();
if (sensorValue > 50 && sensorValue < 200) { // to cut off some static readings only if the reading gets higher then 33 it begings to work
myservo.attach(ServoPin);
//threshold for jittering

// now move the servo to our mapped reading
// Serial.print(“servoValue: “);
// Serial.println(servoValue);
