Hack-24 is a mobile application that integrates with an Arduino-based sensor system to monitor heart rate and detect signs of panic attacks. Upon detecting abnormal heart rate patterns, the app sends a WhatsApp message to a pre-saved contact to notify them of the situation. The app also triggers push notifications for the user to check on their condition.

• Heart Rate Monitoring: Collects real-time heart rate data using an Arduino sensor.
• Panic Detection: Alerts are sent when the heart rate exceeds a panic threshold.
• WhatsApp Notification: Automatically sends a WhatsApp message to a designated contact if a panic attack is detected.
• Push Notifications: Triggers in-app notifications to remind users to check their condition.
• User Interface: Easy-to-use interface to enter contact details, start monitoring, and receive alerts.

• iOS: Swift, UIKit, UserNotifications
• Arduino: C++ for heart rate sensor integration
• Twilio API: For sending WhatsApp messages
• Ngrok: Tunnel API calls to local development server
• HealthKit: To track heart rate data (if connected with Apple Health)
• Adafruit Bluefruit Feather: Arduino-compatible board for hardware monitoring

• Open the Xcode project in the /hack-app folder.
• Make sure to link the required frameworks: UserNotifications, HealthKit, and ORSSerial.
• Add NSHealthShareUsageDescription to Info.plist to request HealthKit authorization.

• Upload the Arduino code from the /arduino-code folder to the Adafruit Bluefruit Feather board.
• Connect the heart rate sensor to the Feather board.
• Ensure that the baud rate for serial communication is set to 9600.

• Set up a Twilio account and configure a WhatsApp sandbox.
• Update your Twilio Account SID, Auth Token, and From number in the server code.

• Install ngrok and set up a tunnel to expose your local server to the internet:bash ngrok http 3000

1. Arduino Setup

   • Connect the sensor to the Arduino board.
   • Upload the provided code for heart rate monitoring.

2. Run the iOS App

   • Open the app on your iOS device.
   • Enter the WhatsApp number for notifications.
   • Start monitoring for panic attack symptoms.

3. WhatsApp Alerts

   • The app will send WhatsApp messages if panic attack symptoms are detected.

4. Push Notifications

   • Push notifications will remind users to check on their heart rate and condition.

The project utilizes the Adafruit Bluefruit Feather for real-time heart rate monitoring via sensors. Ensure that the hardware connections between the Feather board and the sensors are secure.

Components:

• Adafruit Bluefruit Feather
• Heart rate sensor (connected to analog pin)
• LEDs for normal/panic status indicators

The app features a sleek, user-friendly interface with:

• Input fields to save WhatsApp numbers.
• A button to trigger real-time WhatsApp messages when panic symptoms are detected.
• Push notification functionality to alert the user.
