I don't understand what this mean and how to fix it.
int target()
{
long duration = 0;
long distance = 0;
digitalWrite(trigPin, LOW);
delayMicroseconds(2);
digitalWrite(trigPin, HIGH);
delayMicroseconds(10);
digitalWrite(trigPin, LOW);
duration = pulseIn(echoPin, HIGH);
distance = (duration * 0.0343) / 2;
return distance;
}
expected initializer before 'int'

Post your code, in code tags, and we'll try to help you fix it
Where is code tags again.

Yes, that's just the same snippet you posted, equally badly, last time.
i put in the code tags but i don't know how to fix it.

No, you clearly didn't
Where is the rest of your code?
#define trigPin 7
#define echoPin 6
int tank =0;
int phase =0;
void setup() {
// put your setup code here, to run once:
pinMode(13, OUTPUT);
pinMode(12, OUTPUT);
pinMode(9, OUTPUT);
pinMode(8, OUTPUT);
pinMode(10, OUTPUT);
pinMode(11, OUTPUT);
pinMode(2, INPUT);
analogWrite(11, 240);
analogWrite(10, 255);
pinMode(trigPin, OUTPUT);
pinMode(echoPin, INPUT);
Serial.begin(9600);
digitalWrite(13, HIGH);
digitalWrite(12, LOW);
digitalWrite(8, HIGH);
digitalWrite(9, LOW);
}
int target()
{
long duration = 0;
long distance = 0;
digitalWrite(trigPin, LOW);
delayMicroseconds(2);
digitalWrite(trigPin, HIGH);
delayMicroseconds(10);
digitalWrite(trigPin, LOW);
duration = pulseIn(echoPin, HIGH);
distance = (duration * 0.0343) / 2;
return distance;
}
same error.
I only get "undefined reference to `loop'", but that didn't surprise me.
Please remember to use code tags when posting code.
