Your loop function is missing a closing brace and you have two unnecessary ones at the end of your code.

3

Which loop

4

blackwolf97003:
Which loop

The only loop() function

5 
     int servo1 = realservo;
     servo1 = map(servo1, 1000, 1180, 0, 180);

aka

     int servo1 = map(realservo, 1000, 1180, 0, 180);

This

 if(Serial.available() == true){  
   Car_status = Serial.read();  
 }

may not work as you intend (if I'm reading your intent correctly).
If you meant "only read Car_status is there's a single character available", you really ought to use "== 1".

 if(Serial.available() ){  
   Car_status = Serial.read();  
 }

May be more appropriate

Thank a lot it work!
