CarController

This is a simple app to control an Arduino car via Bluetooth. The car has a HC-05 Bluetooth module.

This is the sketch I uploaded to the Arduino board.

char t;

void setup() {
  //to run once:

  pinMode(13,OUTPUT);   //left motors forward
  pinMode(12,OUTPUT);   //left motors reverse
  pinMode(11,OUTPUT);   //right motors forward
  pinMode(10,OUTPUT);   //right motort reverse
  Serial.begin(9600);
}

void loop() {
  //to run repeatedly:
  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(11,HIGH);
  }

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

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

MainActivity

This is the main screen of the app, there are three buttons:
1."Play" button leads to the ControlActivity
2."Connect to Device" leads to the list of available devices
3.Bluetooth icon to disconnect

Devices Activity

In this screen you'll find the list of all the available devices you can connect to

Control Activity

In this screen you'll find the buttons to control the car
