Wheel chair Control using Android Phone

Abstract

The elderly population has grown in recent years. Some live with their children, while others live in their parents' homes or live alone. When elderly people lose their ability to move, problems arise. Not everyone is able to support them whenever they need it. The primary controller, a c Nano and 5V 4 channel relay module, manages the motor, transmits commands to the Bluetooth HC-05 signal receiver, and receives serial data from the Android smartphone.Bluetooth communication protocol is employed in order to connect Android smart phones and controller boxes. The L298N motor driver is used to control the motor's direction and speed.The wheelchair movement can be controlled by using smart phone utilising software and propelling the wheelchair by hand. There are four possible movement directions: Left, right, forward, and backward. The system can also control the flow of electricity by laying down or sitting, thanks to Bluetooth wireless communication. Finally, this product not only enables disabled people to manoeuvre their own wheelchairs without help from others, but it also allows others to control wheel chairs and electrical devices using Android smart phones.
