Arduino Bluetooth Mini Tank

The App sends Bluetooth commands to the Mini Tank: U= Forward, D= Back, L= Left, R= Right, S= Stop

I didn't find any app for my Mini tank on Google Play, so i made one. Enjoy.

CODE:

/*
L = left
R = right
F = forward
B = backward
*/
int pinLB = 12; // define pin 12
int pinLF = 3; // define pin 3
int pinRB = 13; // define pin 13
int pinRF = 11; // define pin 11
int val;
void setup()
{
Serial.begin(9600); // define pin for motor output
pinMode(pinLB,OUTPUT); // pin 12
pinMode(pinLF,OUTPUT); // pin 3 (PWM)
pinMode(pinRB,OUTPUT); // pin 13
pinMode(pinRF,OUTPUT); // pin 11 (PWM)
}
void advance() // move forward
{
digitalWrite(pinLB,LOW); // right wheel moves forward
digitalWrite(pinRB, LOW); // left wheel moves forward
analogWrite(pinLF,255);
analogWrite(pinRF,255);
}
void stopp() // stop
{
digitalWrite(pinLB,HIGH);
digitalWrite(pinRB,HIGH);
analogWrite(pinLF,0);
analogWrite(pinRF,0);
}
void right() // turn right (single wheel)
{

digitalWrite(pinLB,LOW); // left wheel moves forward
digitalWrite(pinRB,HIGH); // right wheel moves backward
analogWrite(pinLF, 255);
analogWrite(pinRF,255);
}
void left() // turn left (single wheel)
{
digitalWrite(pinLB,HIGH); // left wheel moves forward
digitalWrite(pinRB,LOW); // right wheel moves backward
analogWrite(pinLF, 255);
analogWrite(pinRF,255);
}

void back() // move backward
{
digitalWrite(pinLB,HIGH); // motor moves to left rear
digitalWrite(pinRB,HIGH); // motor moves to right rear
analogWrite(pinLF,255);
analogWrite(pinRF,255);
}
void loop()
{
val=Serial.read();
if(val=='U')advance();
if(val=='D')back();
if(val=='L')left() ;
if(val=='R')right();
if(val=='S')stopp();

I did not find any app for my Mini tank on Google Play, so the homemade one. Enjoy.
