Voice Control Using Arduino(Genuino Outside US)

Hello!

This is a voice recognition model built using Arduino uno. The idea behind it is very simple. When we speak something in the android app , the voice is sent as a string in the the HC-05 bluetooth module then the Arduino(Genuino outside US) recieves that string and powers the components according to our commands which are in the program that we uploaded to the board. This could be a very cool project for your science fair...Hope you will like it :)

Step 1: Parts Needed....

1. Arduino(Genuino outside US) UNO x1

2. HC-05 bluetooth module x1

3. 9v battery x1

4. Jumper cables x15

5. Breadboard x1

Step 2: The Circuit...

The circuit is fairly simple. The Arduino is powered by a 9v battery. Connect the jumpers as shown in the circuit diagram. If you face any problem, feel free to contact me.

Step 3: The Code...

String myCommand;

void setup() { Serial.begin(9600); pinMode(3, OUTPUT);// the pins 3,4,5,6 are set to output mode pinMode(4, OUTPUT); pinMode(5, OUTPUT); pinMode(6, OUTPUT);

} //-----------------------------------------------------------------------// void loop() { while (Serial.available()){ //Checks if any byte is there to read delay(10); //it delays the serial by 10 millisecond char c = Serial.read(); //Conduct a serial read myCommand += c; //it builds the string with our commands } if (myCommand.length() > 0) { Serial.println(readvoice);

if(rmyCommand == "a") // pin 3 will be high if command is a { digitalWrite(3,HIGH); digitalWrite(4,LOW); digitalWrite(5,LOW); digitalWrite(6,LOW); delay(100); } else if(myCommand == "b") //pin 4 will be high if command is b { digitalWrite(3,LOW); digitalWrite(4,HIGH); digitalWrite(5,LOW); digitalWrite(6,LOW); delay(100); } else if (myCommand == "c")//pin 5 will be high if command is c { digitalWrite(3,LOW); digitalWrite(4,LOW); digitalWrite(5,HIGH); digitalWrite(6,LOW); delay (100); } else if ( myCommand == "fan")//pin 6 will be high if command is fan { digitalWrite(3,LOW); digitalWrite(4,LOW); digitalWrite(5,LOW); digitalWrite(6,HIGH); delay (100); }

else if( myCommand == "d")//pin 6 will be high if command is d since the fan command may be unreadable by google voice sometimes { digitalWrite(3,LOW); digitalWrite(4,LOW); digitalWrite(5,LOW); digitalWrite(6,HIGH); delay (100); }

else if ( myCommand == "all")//all pins will be high if command is all { digitalWrite(3,HIGH); digitalWrite(4,HIGH); digitalWrite(5,HIGH); digitalWrite(6,HIGH); delay (100); }

else if ( myCommand == "off")//all pins will be low if command is b { digitalWrite(3,LOW); digitalWrite(4,LOW); digitalWrite(5,LOW); digitalWrite(6,LOW); delay (100); } myCommand="";}} // this resets the variable myCommand
