In this project, we are using Bluetooth Module to control wheelchair movements wirelessly. It can be controlled wirelessly using phone having bluetooth support with Android Based Application Software. The bluetooth module is interfaced with microcontroller ATMEGA328 which takes proper actions for the movements of two DC motors. These motors are interfaced with the microcontroller with the motor driver L293D circuit. We are here using Android enabled mobile phone to recognize and process voice commands and send proper commands through bluetooth module in order to control robot movements. Depending upon the commands, the vehicle has movements such as Forward, Reverse, Left, Right, Stop, etc.
