Dhruva's Bluetooth Robot

• Download the free Arduino app on the Arduino website onto your computer/PC and copy the code and paste the code on the Arduino app then connect the USB given with the UNO and connect one to the UNO and the other to the computer.
• Go to tools and on boards select Arduino/Genuino UNO and select the appropriate port as well which the UNO is connected to.
• Then Press the upload button and after it has said “Done Uploading” take the USB out and connect it to your power bank and put it in the sandwiched part of your base, if it doesn’t fit then just put it on top.
• Now connect the 9V battery.
• You need to download the RC Bluetooth Control Car on your phone.
• Then turn on your Bluetooth and press the settings icon, connect to car and select HC-06 or whatever Bluetooth module you have is called and if the light on the left goes from red to green that means it is connected and you can use the buttons now to control your car.
• You will need to disconnect the Rx and Tx pins before uploading the code.

• Here is the code for the Arduino:

char t;

void setup() {
pinMode(13,OUTPUT); //left motors forward
pinMode(12,OUTPUT); //left motors reverse
pinMode(11,OUTPUT); //right motors forward
pinMode(10,OUTPUT); //right motors reverse
pinMode(9,OUTPUT); //Led
Serial.begin(9600);

}

void loop() {
if(Serial.available()){
  t = Serial.read();
  Serial.println(t);
}

if(t == 'F'){
  digitalWrite(13,HIGH);
  digitalWrite(11,HIGH);
}

else if(t == 'B'){
  digitalWrite(12,HIGH);
  digitalWrite(10,HIGH);
}

else if(t == 'L'){
  digitalWrite(13,HIGH);
  digitalWrite(10,HIGH);
}

else if(t == 'R'){
  digitalWrite(11,HIGH);
  digitalWrite(12,HIGH);
}

else if(t == 'W'){
  digitalWrite(9,HIGH);
}
else if(t == 'w'){
  digitalWrite(9,LOW);
}

else if(t == 'S'){
  digitalWrite(13,LOW);
  digitalWrite(12,LOW);
  digitalWrite(11,LOW);
  digitalWrite(10,LOW);
}
delay(100);
}
