Hi, I'm a desperate high school student who is currently in Science Olympiad's Electric Vehicle and I am currently using an arduino uno and a motor shield to program my electric vehicle. My vehicle has four dc motors connected to it and I am currently planning to use motor shield as if all four motors were a single motor because the purpose of the arduino is to get the vehicle to move certain intervals over a predetermined total distance. So far I think I'm heading on the right track but I need someone to please critique and edit my code because I keep getting error messages when verifying.
Thanks
Desperate High School Student

CODE:
void setup() {
// put your setup code here, to run once:
pinMode(3, OUTPUT);
pinMode(4, OUTPUT);
pinMode(5, OUTPUT);
pinMode(6, OUTPUT);
pinMode(7, OUTPUT);
pinMode(8, OUTPUT);
pinMode(9, OUTPUT);
pinMode(10,OUTPUT);
pinMode(11,OUTPUT);


}
void loop(){
digitalWrite(3, HIGH);
digitalWrite(4, HIGH);
digitalWrite(5, HIGH);
digitalWrite(6, HIGH);
digitalWrite(7,HIGH);
digitalWrite(8,HIGH);
digitalWrite(9,HIGH);
digitalWrite(10, HIGH);
digitalWrite(11, HIGH);
digitalWrite(12, HIGH);
digitalWrite(13, HIGH);
delay(10000000000);
digitalWrite(3,LOW);
digitalWrite(4,LOW );
digitalWrite(5, LOW);
digitalWrite(6, LOW);
digitalWrite(7,LOW);
digitalWrite(8,LOW);
digitalWrite(9,LOW);
digitalWrite(10, LOW);
digitalWrite(11 LOW);
digitalWrite(12, LOW);
digitalWrite(13, LOW);
delay(1000);

Don't you think that maybe the error messages would be important for someone to help diagnose the issue(s)??

and what's up with
delay(10000000000);
10 billion milliseconds?
10 million seconds?
115.7 days?
