WheelLink: IoT-Based Smart Wheelchair Control via Blynk App

WheelLink is an advanced IoT-based smart wheelchair control system designed to assist individuals with mobility challenges. The project utilizes a NodeMCU ESP8266 microcontroller for wireless communication and integrates with the Blynk application, allowing users to control wheelchair movement remotely via a smartphone.

Equipped with IR sensors for obstacle detection and gear motors for precise movement, the system ensures safety and smooth navigation. The wheelchair responds to directional commands—forward, backward, left, and right—sent through the Blynk app interface. Additionally, features like an LCD display for status updates and a buzzer for alerts enhance the user experience.

WheelLink demonstrates how IoT and mobile app integration can create smart assistive devices that promote independence and improve the quality of life for users with disabilities. This project is ideal for healthcare innovation, rehabilitation technologies, and smart assistive systems.
