Can't Get Motor to Work, Tried Everything

Thanks for the help.

I didn't know that there were screws along the sides. I was plugging the wires from my DC motor into those holes next to each screw. So, I'm suppose to put a wire into the holes where the screws are and then screw the screw back into the hole while the wire is still in there to use that terminal? I could somehow touch the wire to the screw too such as soldering, right?

As for the servo motor, I connected it as shown in the picture I uploaded and ran the code I posted below.

I have the Arduino plugged into USB from my computer and nothing happens. I installed the Adafruit Motor Shield library and this code is from the "Motor Party" example. What am I doing wrong? I have a 9V battery I could connect to either the Arduino or Motor Shield, will this help?

  Serial.begin(9600);           // set up Serial library at 9600 bps
  Serial.println("Motor party!");
  
  // turn on servo
  servo1.attach(9);
   
  // turn on motor #2
  motor.setSpeed(200);
  motor.run(RELEASE);
}

int i;

// Test the DC motor, stepper and servo ALL AT ONCE!
void loop() {
  motor.run(FORWARD);

    servo1.write(i);
