Arduino Rover with IR remote not working

Using Arduino Project Guidance
#1

Hello, I am having trouble with a project i have. I am using arduino uno with the arduino motor shield r3 and an infrared receiver.

The idea is that i control the rover with the remote. I have a library called IRremote that helps me with getting remote codes.

The problem is, the motors for the wheels don’t move at all. I have tested the wires and all the connections are well connected and insulated. The lights that are next to the motor ports on the motor shield stay off when they are supposed to be on.

 * Lets get started:
 
 The IR sensor's pins are attached to Arduino as so:
 Pin 1 to Vout (pin 11 on Arduino)
 Pin 2 to GND
 Pin 3 to Vcc (+5v from Arduino)

    Serial.println("Middle Button Pressed");
    digitalWrite(12, HIGH);
    digitalWrite(9, HIGH);  
    analogWrite(3, 0);  

  
    digitalWrite(13, HIGH);
    digitalWrite(8, HIGH);
    analogWrite(11, 0);
  }
  
}

Someone please help!

//Setup Channel B
  pinMode(13, OUTPUT); //Initiates Motor Channel A pin
  pinMode(8, OUTPUT);  //Initiates Brake Channel A pin

Your code would be a lot easier to read and maintain if the pins had sensible names, then you could get rid of the comments that don’t agree.

#3

Your comments say the IR receiver is connected to pin 11 and the code says pin 2....

 Pin 1 to Vout (pin 11 on Arduino)
.......
int IRpin = 2;

Consider reviewing your wiring, comments or coding!
