Can someone help me debug why this is not giving my motor any movement.

#include

int PUL = 4; // define pin pulse

int DIR = 3; // define Direction pin

int ENA = 2; // define Enable Pin

//Motor2

int PUL2 = 7; // define pin pulse

int DIR2 = 6; // define Direction pin

int ENA2 = 5; // define Enable Pin

//#include "Ultrasonic.h"

int trigPin = 8;

int echoPin = 9;

//Ultrasonic ultrasound (trigPin, echoPin);

int dis = 20;

int distance;

int pinServo = 10; // Digital pin with PWM for the Servo

int pulseMin = 650; // Pulse in us to rotate an angle of 0

int pulseMax = 255; // Pulse in us to rotate a 180 angle

int angle = 0; // Variable to save the angle of the servo

int from = 0;

int to = 120;

int step = 1;

int ledrele = 11;

void setup () {

servo1.attach (pinServo, pulseMin, pulseMax);

pinMode (trigPin, OUTPUT);

pinMode (echoPin, INPUT);

pinMode (ledrele, OUTPUT);

digitalWrite (ledrele, LOW);

}

void loop () {

angle += step;

servo1.write (angle);

delay (15);

if (angle >= 120) {

step = -1;

from = 120;

// up = 0;

}

if (angle == 0) {

step = 1;

from = 0;

to = 120;

}

// distance = ultrasound.Ranging (CM);

if (distance

advance();

} else {

stop();

}

}
