Project 1

Originally I wanted this project to be a peaceful noise and was leaning more towards a white noise machine. I changed my mind last week when I was overloaded with homework and my anxiety was through the roof about it. Personally, I can't sleep when I know I have things that need to be finished so I moldeled my Arduino after what I feel at night while trying to rest knowing I have homework. I chose to make it look like a cloud to represent me trying to relax but it makes a loud alarm sound which represents my mind racing and not letting me get any rest. 

​

CODE:

int ledPin = 13;

int buzzerPin = 12;

int ldrPin = A0;

void setup() {

  Serial.begin(9600);

  pinMode(ledPin, OUTPUT);

  pinMode(buzzerPin, OUTPUT);

  pinMode(ldrPin, INPUT);

}

void loop() {

  int ldrStatus = analogRead(ldrPin); 

  if (ldrStatus <= 400) {

    tone(buzzerPin, 100);

    digitalWrite(ledPin, HIGH);

    delay(100);

    noTone(buzzerPin);

    digitalWrite(ledPin, LOW);

    delay(100);

    Serial.println("HOMEWORK");

  }

  else {

    noTone(buzzerPin);

    digitalWrite(ledPin, LOW);

    Serial.println("slightly less homework");

  }

}
