2. Firebase Sync:
   • Data is pushed to Firebase in real-time.
3. Raspberry Pi Actions:
   • Fetches schedule from Firebase.
   • Compares current time.
   • Dispenses tablet using servo motor.
   • Triggers buzzer/speaker.
   • Updates database with success/failure and inventory count.
4. Mobile App Alerts:
   • User receives notification on dosage, missed doses, or low stock.
