automatic control wheelchair

🖐️ Gesture-based control system using hand movements to operate the wheelchair.

🤖 Arduino Nano is used to process gesture signals and control motor movement.

📦 ADXL335 accelerometer detects the tilt direction of the user’s hand.

📡 NRF24L01 wireless modules enable communication between hand unit and wheelchair.

⚙️ Motor driver (L293D) controls the DC motors to move in all four directions.

🔋 Battery-powered system with lightweight and rechargeable lithium cells.

🦽 Wheelchair moves forward, backward, left, and right based on hand tilt.

🧠 Real-time signal processing allows smooth and intuitive motion control.

🎯 Ideal for science fairs, engineering exhibitions, and final-year projects.

🧩 Great learning project to explore sensors, wireless tech, and embedded systems.

💡 Promotes assistive innovation for differently-abled individuals using simple electronics.
