Adafruit Motor Shield Code HELP!

I want to be able to use a TV remote to gradually increase and decrease the speed of motor hooked up to the Adafruit Motor shield, and all my attempts have failed. Here’s the code(that doesn’t work):

#include <IRremote.h> // use the library

int receiver = 2; // pin 1 of IR receiver to Arduino digital pin 11

IRrecv irrecv(receiver); // create instance of 'irrecv'

decode_results results;

#include <AFMotor.h>

AF_DCMotor motor(1);

int val = 0;

void setup()


  Serial.begin(9600); // for serial monitor output

  irrecv.enableIRIn(); // Start the receiver

void translateIR() // takes action based on IR code received




    case 0x70: Serial.println("Menu/Exit"); break;

    case 0xA90: Serial.println("Power"); break;

    case 0x290: Serial.println("Mute"); break;

    case 0x90: Serial.println("Ch +"); break;

    case 0x890: Serial.println("Ch -"); break;

    case 0xA70: Serial.println("Select/OK"); break;

    case 0xC90: Serial.println("Vol -"); break;

    case 0x490: Serial.println("Vol +"); break;
    case 0x710: Serial.println("Guide"); break;

    case 0x2F0: Serial.println("Up");{
      val = val + 10;
      val = constrain(val, 0, 255);
    case 0xAF0: Serial.println("Down");break;
    case 0x2D0: Serial.println("Left");break;
    case 0xCD0: Serial.println("Right"); break;

    case 0x910: Serial.println("0"); break;

    case 0x5D0: Serial.println("Info"); break;

    case 0x10: Serial.println("1"); break;

    case 0x810: Serial.println("2"); break;

    case 0x410: Serial.println("3"); break;

    case 0xC10: Serial.println("4"); break;

    case 0x210: Serial.println("5"); break;
    case 0xA10: Serial.println("6"); break;
    case 0x610: Serial.println("7"); break;
    case 0xE10: Serial.println("8"); break;
    case 0x110: Serial.println("9"); break;
    case 0xD10: Serial.println("Enter"); break;
    case 0x9B0: Serial.println("Page Dwn"); break;
    case 0x1B0: Serial.println("Page Up"); break;
    case 0xA50: Serial.println("Input"); break;
    case 0xDD0: Serial.println("-/Prev.Ch"); break;
    case 0x425: Serial.println("CC"); break;
    case 0xCB0: Serial.println("Play"); break;
    case 0x5B0: Serial.println("Record"); break;
    case 0x2B0: Serial.println("Pause"); break;
    case 0xAB0: Serial.println("Stop"); break;
    case 0xEB0: Serial.println("Skip Back"); break;
    case 0x6B0: Serial.println("Skip Forward"); break;
    case 0xFFFFFFFF: break;

    default:  Serial.print("Other button:"); Serial.println(results.value,HEX);





void loop()


  if (irrecv.decode(&results)) // have we received an IR signal?



    for (int z=0; z<2; z++) // ignore 2nd and 3rd signal repeat


      irrecv.resume(); // receive the next value




It compiles correctly, uploads correctly, receives button pushes from the remote correctly, and prints the speed (val) of the motor correctly. Here’s the problem: the motor doesn’t move! I can get the motor to run just fine with the example code provided with the library, but this code just doesn’t work. I am sure that this is a code issue, not a hardware issue. Any help is greatly appreciated!!!

What does the example code look like? In particular, which number motor does it use? i.e. have you chosen the wrong one in your example? I also note that you haven't set the PWM frequency - does it matter?

int receiver = 2; // pin 1 of IR receiver to Arduino digital pin 11

That comment really helps. Now I know for sure what is connected to what. Not!
