I am using an Arduino Uno with an EasyVR Sheild. I am trying to turn an LED on when I say ANNA to activate it, then say, GREEN_LED. This LED is fading on and off. Please help me if possible. The code is bellow.


#if defined(ARDUINO) && ARDUINO >= 100
  #include "Arduino.h"
  #include "SoftwareSerial.h"
  SoftwareSerial port(12,13);
#else // Arduino 0022 - use modified NewSoftSerial
  #include "WProgram.h"
  #include "NewSoftSerial.h"
  NewSoftSerial port(12,13);
#endif

#include "EasyVR.h"
EasyVR easyvr(port);

//Groups and Commands
enum Groups
{
  GROUP_0  = 0,
  GROUP_1  = 1,
};

enum Group0
{
  G0_ANNA = 0,
};

enum Group1
{
  G1_GREEN_LED = 0,
};


EasyVRBridge bridge;

int8_t group, idx;
int led = 9;           // the pin that the LED is attached to
int brightness = 0;    // how bright the LED is
int fadeAmount = 5;    // how many points to fade the LED by
int ledloop

void setup()  {
   // declare pin 9 to be an output:
  pinMode(led, OUTPUT);
 
  // bridge mode?
  if (bridge.check())
  {
    cli();
    bridge.loop(0, 1, 12, 13);
  }
  // run normally
  Serial.begin(9600);
  port.begin(9600);

  if (!easyvr.detect())
  {
    Serial.println("EasyVR not detected!");
    for (;;);
  }

  easyvr.setPinOutput(EasyVR::IO1, LOW);
  Serial.println("EasyVR detected!");
  easyvr.setTimeout(5);
  easyvr.setLanguage(0);

  group = EasyVR::TRIGGER; //<-- start group (customize)
}

void action();

void loop()
{
  easyvr.setPinOutput(EasyVR::IO1, HIGH); // LED on (listening)

  Serial.print("Say a command in Group ");
  Serial.println(group);
  easyvr.recognizeCommand(group);

  do
  {
    // can do some processing while waiting for a spoken command
  }
  while (!easyvr.hasFinished());
 
  easyvr.setPinOutput(EasyVR::IO1, LOW); // LED off

  idx = easyvr.getWord();
  if (idx >= 0)
  {
    // built-in trigger (ROBOT)
    // group = GROUP_X; <-- jump to another group X
    return;
  }
  idx = easyvr.getCommand();
  if (idx >= 0)
  {
    // print debug message
    uint8_t train = 0;
    char name[32];
    Serial.print("Command: ");
    Serial.print(idx);
    if (easyvr.dumpCommand(group, idx, name, train))
    {
      Serial.print(" = ");
      Serial.println(name);
    }
    else
      Serial.println();
    easyvr.playSound(0, EasyVR::VOL_FULL);
    // perform some action
    action();
  }
  else // errors or timeout
  {
    if (easyvr.isTimeout())
      Serial.println("Timed out, try again...");
    int16_t err = easyvr.getError();
    if (err >= 0)
    {
      Serial.print("Error ");
      Serial.println(err, HEX);
    }
  }
}

void action()
{
    switch (group)
    {
    case GROUP_0:
      switch (idx)
      {
      case G0_ANNA:
        // write your action code here
        // group = GROUP_X; <-- or jump to another group X for composite commands
        group = GROUP_1;
        break;
      }
      break;
    case GROUP_1:
      switch (idx)
      {
      case G1_GREEN_LED:
        // write your action code here
        goto ledloop;
        // group = GROUP_X; <-- or jump to another group X for composite commands
      }
      break;
}
void ledloop()  {
  // set the brightness of pin 9:
  analogWrite(led, brightness);   

  // change the brightness for next time through the loop:
  brightness = brightness + fadeAmount;

  // reverse the direction of the fading at the ends of the fade:
  if (brightness == 0 || brightness == 255) {
    fadeAmount = -fadeAmount ;
  }     
  // wait for 30 milliseconds to see the dimming effect   
  delay(30);                           
}
