The man who eats cotton

by Luiza Stibe & Stella Tan

Project Image	In Action

Save the man by removing the excessive cotton in his stomach! Be very gentle though, he is afraid of pain and he’ll shout at you if you hurt him.

Arduino Code

int buzzer = 7;
int photoresistor1 = A0;
int photoresistor2 = A1; 
int LED = 8;

void setup()
{
  Serial.begin(9600); 
  pinMode(LED,OUTPUT);
  pinMode(buzzer, OUTPUT);
}

void loop()

{
int lightValue1 = analogRead(photoresistor1);
int lightValue2 = analogRead(photoresistor2);

Serial.println(lightValue1);

if(lightValue1<400 || lightValue2<400) {
  digitalWrite(LED,HIGH);
  tone(buzzer, 330);
  }
  else{

  digitalWrite(LED,LOW); 
  noTone(buzzer); }

  }
