1x Stuffed Animal
1x Breadboard
1x Arduino
3x LED's
1x 100 or 220 Ohm Resistor

The Code:

int flashrate = 0;
void setup() {
  pinMode(13, OUTPUT);
  delay(2000);
}
void loop() {
void loop() {  int sensorValue = analogRead(A0);
  int flashrate = sensorValue * .9;
      if (sensorValue > 80 ) {
analogWrite(3, 150);   
digitalWrite(13, HIGH);
delay(30);
  digitalWrite(3, LOW);
  delay(flashrate);
  digitalWrite(13, LOW);
  delay(flashrate);
      }
    if (sensorValue < 80 ) {
    analogWrite(3, 150);
    digitalWrite(13, LOW);
  }
  }
