Face Recognition Based Attendance System Using IoT 👤📋
Built an IoT-integrated attendance system that replaces manual roll calls with real-time face recognition — a camera captures each person as they arrive, matches their identity, and logs attendance automatically to a live dashboard.
Stack: Python · OpenCV · Face Recognition · IoT
How it works:
📷 IoT camera captures a live face
🔍 OpenCV detects the face region
🧠 Recognition model matches it against known identities
📝 Attendance is logged with a timestamp
📡 Status is pushed to a connected dashboard in real time
This project came out of wanting to solve a genuinely everyday problem — attendance tracking — using computer vision and IoT together instead of paperwork or manual entry. Open to adapting this into a classroom, office, or event check-in system.

Bluetooth-Controlled Home Automation 📱🏠
Built a Python-based prototype enabling wireless remote control of household appliances over Bluetooth — turning a simple phone or PC command into real-world hardware action.
Stack: Python · Bluetooth Protocol (HC-05) · Embedded Systems · IoT
How it works:
📲 Python client connects via Bluetooth (RFCOMM)
📡 Command is sent through the HC-05 Bluetooth module
🔌 Arduino decodes the appliance ID + ON/OFF state
💡 Relay switches the appliance (light, fan, TV, plug)
A hands-on dive into wireless embedded systems — happy to walk through the setup or adapt this into a smart home solution tailored to your needs.

Voice-Controlled Robot 🎙️🤖
Built a hands-free robot using Python speech recognition paired with Arduino microcontroller programming — turning spoken commands into real-time motion control.
Stack: Python (SpeechRecognition) · Arduino · IoT
How it works:
🎤 Microphone captures a voice command
🗣️ Speech is converted to text via recognition API
🔀 Command is mapped to a motor instruction
⚙️ Arduino executes the movement (forward, back, left, right, stop)
A fun deep-dive into combining Python with embedded hardware — glad to explain the architecture or build something similar for a voice-driven automation use case.

AI-Based Waste Segregation Model 🗑️♻️
Built a CNN-based image classification system in Python to automate waste categorization in real time — sorting items into organic, recyclable, and hazardous categories to support smarter waste management systems.
Stack: Python · TensorFlow/Keras · OpenCV · CNNs
How it works:
📷 Camera captures a live frame
🔄 Image is preprocessed and resized
🧠 A CNN classifies the waste type
✅ Output feeds into automated sorting
This was built during my exploration into applying deep learning to real-world sustainability problems — happy to walk through the architecture or adapt something similar for your use case.
