Smart Wheelchair

An Arduino-based smart wheelchair that supports both joystick and Bluetooth control for improved mobility and accessibility.

Joystick Manual Control
Bluetooth Wireless Control
Buzzer Horn Alert

Project Overview

This Smart Wheelchair combines a joystick module and Bluetooth communication to provide flexible mobility control. Users can operate the wheelchair manually using the joystick or wirelessly through a smartphone application.

The Arduino processes joystick inputs and Bluetooth commands, controls the motor driver, and manages a buzzer horn system for enhanced safety and accessibility.
