Unit 26: Handle with care

 

 

 

Code for Sketch One: 

const int tiltPin = 13;   // Tilt sensor connected to pin 13
const int buzzerPin = 3;  // Buzzer connected to pin 3
const int buttonPin = 7;  // Button connected to pin 7

void setup() {
  pinMode(tiltPin, INPUT);               // Set tilt sensor as input
  pinMode(buzzerPin, OUTPUT);            // Set buzzer as output
  pinMode(buttonPin, INPUT_PULLUP);      // Enable internal pull-up for button
  Serial.begin(9600);                    // Begin Serial communication
}

void loop() {
  int tiltState = digitalRead(tiltPin);   // Read the state of the tilt sensor
  int buttonState = digitalRead(buttonPin); // Read the state of the button
  
  Serial.print("Tilt State: ");
  Serial.println(tiltState);
  Serial.print("Button State: ");
  Serial.println(buttonState);

  // If the tilt sensor is triggered and the button is not pressed
  if (tiltState == LOW && buttonState == HIGH) {
    Serial.println("Buzzer ON");
    digitalWrite(buzzerPin, HIGH); // Turn on buzzer
  } else {
    Serial.println("Buzzer OFF");
    digitalWrite(buzzerPin, LOW); // Turn off buzzer
  }

  delay(500); // Delay for stability
}


  

Code for Sketch Two

 const int tiltPin = 13;    // Tilt sensor connected to pin 13
const int buzzerPin = 3;   // Buzzer connected to pin 3
const int buttonPin = 7;   // Button connected to pin 7
int tiltCount = 0;         // Count the number of tilt triggers

void setup() {
  pinMode(tiltPin, INPUT);
  pinMode(buzzerPin, OUTPUT);
  pinMode(buttonPin, INPUT_PULLUP);  // Button setup with internal pullup
  Serial.begin(9600);                // Initialize serial communication
}

void loop() {
  int tiltState = digitalRead(tiltPin);
  int buttonState = digitalRead(buttonPin);

  Serial.print(“Tilt State: “);
  Serial.println(tiltState);
  Serial.print(“Button State: “);
  Serial.println(buttonState);
  Serial.print(“Tilt Count: “);
  Serial.println(tiltCount);

  // If tilt sensor is triggered, increase the tilt count
  if (tiltState == LOW) {   // Tilt detected (LOW means triggered)
    tiltCount++;
    Serial.println(“Tilt Detected, Count Increased”);
    delay(500);  // Delay to avoid multiple counts for a single tilt
  }

  // If the count exceeds 3, activate the buzzer
  if (tiltCount > 3) {
    Serial.println(“Buzzer ON - Alarm Triggered!”);
    digitalWrite(buzzerPin, HIGH);  // Turn on the buzzer
  }

  // If the button is pressed, reset the counter and buzzer
  if (buttonState == LOW) {  // Button pressed (LOW means pressed)
    tiltCount = 0;           // Reset the tilt counter
    digitalWrite(buzzerPin, LOW);  // Turn off the buzzer
    Serial.println(“Button Pressed - Counter Reset”);
    delay(500);  // Debounce delay for the button press
  }

  delay(100);  // Stability delay
}
