Hi,
Try this code with post #59 diagram, BUT connect EN1 to pin 9, pin 7 is not a PWM pin.

// constants won't change
const int ENA_PIN = 9; // the Arduino pin connected to the EN1 pin L298N
const int IN1_PIN = 6; // the Arduino pin connected to the IN1 pin L298N
const int IN2_PIN = 5; // the Arduino pin connected to the IN2 pin L298N
// the setup function runs once when you press reset or power the board
void setup()
{
Serial.begin(9600);
Serial.println("Setup Running");
// initialize digital pins as outputs.
pinMode(ENA_PIN, OUTPUT);
pinMode(IN1_PIN, OUTPUT);
pinMode(IN2_PIN, OUTPUT);
}
// the loop function runs over and over again forever
void loop()
{
Serial.println("Top Of Loop");
delay(250); //for diagnostic reasons.
digitalWrite(IN1_PIN, HIGH); // control motor A spins clockwise
digitalWrite(IN2_PIN, LOW); // control motor A spins clockwise
for (int motspeed = 0; motspeed <= 255; motspeed++)
{
analogWrite(ENA_PIN, motspeed); // control the speed
Serial.println(motspeed);
delay(10);
}
delay(1000); // rotate at maximum speed 1 seconds in in clockwise direction
Serial.print("Change direction");
delay(250);
// change direction
digitalWrite(IN1_PIN, LOW); // control motor A spins anti-clockwise
digitalWrite(IN2_PIN, HIGH); // control motor A spins anti-clockwise
delay(1000); // rotate at maximum speed 1 seconds in in anti-clockwise direction
for (int motspeed = 255; motspeed >= 0; motspeed--)
{
analogWrite(ENA_PIN, motspeed); // control the speed
Serial.println(motspeed);
delay(10);
}
Serial.println("Stop motor");
delay(1000); // stop motor 1 second
Serial.println("Change direction");
delay(250);
}
Open the IDE monitor at 9600.

PS, Check the continuity of your jumper leads...
