Arduino UNO + RGB pixels strand + voice control

Hello,

Have following issue to clarify. I have:

#include "SPI.h"
#include "Adafruit_WS2801.h"

/*****************************************************************************
Example sketch for driving Adafruit WS2801 pixels!


  Designed specifically to work with the Adafruit RGB Pixels!
  12mm Bullet shape ----> https://www.adafruit.com/products/322
  12mm Flat shape   ----> https://www.adafruit.com/products/738
  36mm Square shape ----> https://www.adafruit.com/products/683

  These pixels use SPI to transmit the color data, and have built in
  high speed PWM drivers for 24 bit color per pixel
  2 pins are required to interface

  Adafruit invests time and resources providing this open source code, 
  please support Adafruit and open-source hardware by purchasing 
  products from Adafruit!

// Choose which 2 pins you will use for output.
// Can be any valid output pins.
// The colors of the wires may be totally different so
// BE SURE TO CHECK YOUR PIXELS TO SEE WHICH WIRES TO USE!
uint8_t dataPin  = 2;    // Yellow wire on Adafruit Pixels
uint8_t clockPin = 3;    // Green wire on Adafruit Pixels

// Don't forget to connect the ground wire to Arduino ground,
// and the +5V wire to a +5V supply

// Set the first variable to the NUMBER of pixels. 25 = 25 pixels in a row
Adafruit_WS2801 strip = Adafruit_WS2801(25, dataPin, clockPin);

// Optional: leave off pin numbers to use hardware SPI
// (pinout is then specific to each board and can't be changed)
//Adafruit_WS2801 strip = Adafruit_WS2801(25);

// For 36mm LED pixels: these pixels internally represent color in a
// different format.  Either of the above constructors can accept an
// optional extra parameter: WS2801_RGB is 'conventional' RGB order
// WS2801_GRB is the GRB order required by the 36mm pixels.  Other
// than this parameter, your code does not need to do anything different;
// the library will handle the format change.  Examples:
//Adafruit_WS2801 strip = Adafruit_WS2801(25, dataPin, clockPin, WS2801_GRB);
//Adafruit_WS2801 strip = Adafruit_WS2801(25, WS2801_GRB);

      strip.setPixelColor(i, Wheel( (i + j) % 255));
    }  
    strip.show();   // write all the pixels out
    delay(wait);

Need to control RGB strand of 20 pixels via voice. Firstly just a sequence that fills the strip with a color.

Ok, so what's your issue?

Issue is: to connect two codes. Have tryied and got something:

#include <SPI.h>
#include <Adafruit_WS2801.h>


int light_data  = 2;    // Yellow wire on Adafruit Pixels
int light_clk = 3;    // Green wire on Adafruit Pixels

Adafruit_WS2801 strip = Adafruit_WS2801(20, light_data, light_clk);

//??? ??? ?????????? ??????:
/*
int redPin = 11; // R petal on RGB LED module connected to digital pin 11
int greenPin = 9; // G petal on RGB LED module connected to digital pin 9
int bluePin = 10; // B petal on RGB LED module connected to digital pin 10
*/
byte com = 0; //reply from voice recognition


/*void color (unsigned char red, unsigned char green, unsigned char blue) // the color generating function
{ 
analogWrite(redPin, red*102/255); 
analogWrite(bluePin, blue*173/255);
analogWrite(greenPin, green*173/255);
}
*/






void setup() 
{ 
Serial.begin(9600);

//pinMode(redPin, OUTPUT); // sets the redPin to be an output
//pinMode(greenPin, OUTPUT); // sets the greenPin to be an output
//pinMode(bluePin, OUTPUT); // sets the bluePin to be an output

Does anyone know how to record the voice commands? The access software is not quite clear.

You have similar voice module as me ?

Yea I do, and I figured it out after an hour of messing with it.
