this is my code

double ___eroare;
double ___senzori;

int _input_SA4 = A4;
int _led_L = 13;

void citesteSenzoriAnalogi() {
___SA0 = analogRead(_input_SA0);
___SA1 = analogRead(_input_SA1);
___SA2 = analogRead(_input_SA2);
___SA3 = analogRead(_input_SA3);
___SA4 = analogRead(_input_SA4);
}

void calculEroare() {
if ( ___SA2 < 200 ) {
___eroare = 0;
} else {
if ( ( ___SA0 < 200 ) || ( ___SA1 < 200 ) ) {
___eroare = 1;
} else {
if ( ( ___SA3 < 200 ) || ( ___SA4 < 200 ) ) {
___eroare = -1;
}
}
}
}

void controlMotoare() {
digitalWrite(_output_PD4, 1);
digitalWrite(_output_PD5, 0);
digitalWrite(_output_PD6, 0);
digitalWrite(_output_PD7, 1);
if ( ___eroare == 0 ) {

analogWrite(_output_PWM9, 80);
analogWrite(_output_PWM10, 0);
} else {
analogWrite(_output_PWM9, 0);
analogWrite(_output_PWM10, 80);
}
}
}

First go read the forum guide in the sticky post.

Next, edit and fix your post above so it doesn't break forum rules, and includes the other things recommended in the guide.

Please do not post in "Uncategorized"; see the sticky topics in Uncategorized - Arduino Forum. Topic has been moved.

Please edit your post, select all code and click the <CODE/> button; next save your post. This will apply code tags which makes it easier to read and easier to copy and the forum software will display it correctly.

Please read How to get the best out of this forum; you topic is lacking information. Among these (but not necessarily limited to):

  • Which board.
  • What happens? How does that differ from what you expect?
  • What do your serial prints tell you (no image please).
  • Wiring diagram how everything is connected.
  • Information how it all is powered.

A cable might be broken or connected to the wrong pin.
Wrong type of sensor.
