CODING IN ARDUINO

CODING IN ARDUINO:
The open-source Arduino Programming (IDE) makes it simple to compose code and transfer it
to the board. It keeps running on Windows, Macintosh OS X, and Linux. Nature is composed in
Java and in light of Handling and other open-source programming.
For auto mode:
void AutoMode()
{
if(ResetCheck == 0)
{
if(PIRValue == 1)
{
radio.stopListening();
unsigned long time = 1;
radio.write( &time, sizeof(unsigned long) );
radio.startListening();
MotorsStop();
while(1)
{
PIRSensor();
if ( radio.available() )
{
unsigned long data = 0;
radio.read( &data, sizeof(unsigned long) );
Serial.println(data);

if(data == 9){direc = 6;}
}
if(direc == 6)
{
ResetCheck = 1;
direc = 0;
break;
}
if(PIRValue == 0){break;}
}
}
if(PIRValue == 0)
{
//Serial.println("YES");

}
}
if(FrontSensor > 50 ){ MotorsForward(); }
if(FrontSensor < 50)
{
MotorsStop();
delay(1000);
if(((RightSensor > 30) && (LeftSensor > 30)) && (TurnCheck == 0))
{
MotorsLeft();
delay(3500);
MotorsStop();
delay(1000);
//MotorsForward();
TurnCheck = 1;
}
if((RightSensor < 30) && (LeftSensor < 30))
{

MotorsStop();
StopCheck = 1;
}
if(StopCheck == 0)
{
if((RightSensor < 30) && (TurnCheck == 0))
{
MotorsLeft();
delay(3500);
MotorsStop();
delay(1000);
//MotorsForward();
TurnCheck = 1;
}
if((LeftSensor < 30) && (TurnCheck == 0))
{
MotorsRight();
delay(3500);
MotorsStop();
delay(1000);
//MotorsForward();

TurnCheck = 1;
}
}
StopCheck = 0;
TurnCheck = 0;
}
}
For Manual Mode:-
void ManualMode()
{
if(direc == 1){MotorsForward();}
if(direc == 2){MotorsBackward();}
if(direc == 3){MotorsLeft();}
if(direc == 4){MotorsRight();}
if(direc == 5){MotorsStop();}
if(PIRValue == 1)
{
MotorsStop();

while(1)
{
PIRSensor();
if(PIRValue == 0){break;}
}
}
if(PIRValue == 0)
{
//Serial.println("YES");
}
}
