The uploading code

## In the firstly daowload Arduino IDE (https://www.arduino.cc/en/software),with this we can upload the code

char t;
 
void setup() {
pinMode(13,OUTPUT);   
pinMode(11,OUTPUT);   
pinMode(10,OUTPUT);   
pinMode(9,OUTPUT);   
pinMode(8,OUTPUT);   

pinMode(A3,OUTPUT); 
pinMode(A2,OUTPUT); 
pinMode(A1,OUTPUT);
Serial.begin(9600);
 
}
 
void loop() {
if(Serial.available()){
  t = Serial.read();
  Serial.println(t);
}
 
if(t == 'F'){            
  digitalWrite(13,HIGH);
  digitalWrite(10,HIGH);
}
 
else if(t == 'B'){      
  digitalWrite(11,HIGH);
  digitalWrite(9,HIGH);
  digitalWrite(A3,HIGH);
}
 
else if(t == 'L'){      
  digitalWrite(10,HIGH);
  digitalWrite(A2,HIGH);
}
 
else if(t == 'R'){     
  digitalWrite(13,HIGH);
 digitalWrite(A1,HIGH);
}

else if(t == 'W'){    
  digitalWrite(8,HIGH);
}
else if(t == 'w'){
  digitalWrite(8,LOW);
}
 
else if(t == 'S'){      
  digitalWrite(13,LOW);
  digitalWrite(11,LOW);
  digitalWrite(10,LOW);
  digitalWrite(9,LOW);
  digitalWrite(A3,LOW);
  digitalWrite(A2,LOW);
  digitalWrite(A1,LOW);
}
delay(100);
