Voice and Button Automation for Disabled

INTRO:

The biggest problem in disabled persons is their inability to access things easily as others. But, our modern technologies and our super brain has made them possible to achieve great heights. This project is a Arduino-based project used to give home automation through voice and buttons which is available in my own android application made with MIT app inventor ."Talk less work more", So let's begin:)

The supplies required for this project are:

Arduino UNO / Arduino NANO

Bluetooth module HC-05 / HC-06

Relay module ( not used in video )

Bluetooth app (given)

Arduino IDE

Few minutes

jumper wires

wire extension box ( not used in video )

Any appliance (fan , light ,phone)

BLUETOOTH MODULE - ARDUINO

VCC >> 5V

GND >>GND

TX >> RX

RX >> TX

LED - ARDUINO

LED 1 - ARDUINO

SMALL LEG (CATHODE) >> GND

LONG LEG (ANODE) >> 3

LED 2 - ARDUINO
SMALL LEG (CATHODE) >> GND

LONG LEG (ANODE) >> 3

LED 3 - ARDUINO
SMALL LEG (CATHODE) >> GND

LONG LEG (ANODE) >> 3

LED 4 - ARDUINO
SMALL LEG (CATHODE) >> GND

LONG LEG (ANODE) >> 3

BLUETOOTH APP FOR ARDUINO

BLUETOOTH APP FOR ARDUINO IS VERY IMPORTANT.

I HAVE USED MIT APP INVENTOR TO CREATE ONE

THE APP IS GIVEN:

https://drive.google.com/open?id=1B_BuBoj6zpGicyffwOf7ZPOfiJ98bq18

THE MOST IMPORTANT THING - CODE IS TO BY GIVEN IN ARDUINO IDE

CODE:

IF THE CODE GIVEN HERE DOESNT WORK, USE THIS GOOGLE DRIVE CODE:

TIME FOR TEST:

TESTING IS GIVEN IN THE LAST PART OF THE VIDEO

https://youtu.be/HxYhx9T9x6w

USE THE LED TO TEST AS IT IS SAFE

ENJOY THE PROJECT THANK YOU!
