Hi.. can you please let me know the flora code to blink led pixel and fade code also ?

thanks

Can you be more specific? How many pixels? Fade from what color to what color?

Have you tried the example code from the guide? http://learn.adafruit.com/flora-rgb-sma ... -test-code

You haven't given us any details about how many pixels you have or how they are wired. But this should blink one pixel connected to pin 6:

Code: Select all


#define LEDPIN 6;

Adafruit_NeoPixel strip = Adafruit_NeoPixel(1, LEDPIN, NEO_GRB + NEO_KHZ800);


void setup() 
{
  strip.begin();
  strip.show(); // Initialize all pixels to 'off'
}

void loop() 
{
  strip.setPixelColor(0, strip.Color(255,255,255)); // white
  strip.show();
  delay(1000);
  
  strip.setPixelColor(0, strip.Color(0,0,0)); // black
  strip.show();
  delay(1000);
}

hi....sorry i am new in it i am not able to upload this code please see that attached pic with uploading error and i am using 4 pixels please send correct code. i want all the effects in 1 one code like blink then fade and then colors change. send me any simple code that i can change according to me. i am using this below code for led strip ws2801 send me something like this

Code: Select all

/*
  Nathan Seidle
  SparkFun Electronics 2011
  
  This code is public domain but you buy me a beer if you use this and we meet someday (Beerware license).
  
  Controlling an LED strip with individually controllable RGB LEDs. This stuff is awesome.
  
  The SparkFun (individually controllable) RGB strip contains a bunch of WS2801 ICs. These
  are controlled over a simple data and clock setup. The WS2801 is really cool! Each IC has its
  own internal clock so that it can do all the PWM for that specific LED for you. Each IC
  requires 24 bits of 'greyscale' data. This means you can have 256 levels of red, 256 of blue,
  and 256 levels of green for each RGB LED. REALLY granular.
 
  To control the strip, you clock in data continually. Each IC automatically passes the data onto
  the next IC. Once you pause for more than 500us, each IC 'posts' or begins to output the color data
  you just clocked in. So, clock in (24bits * 32LEDs = ) 768 bits, then pause for 500us. Then
  repeat if you wish to display something new.
  
  This example code will display bright red, green, and blue, then 'trickle' random colors down 
  the LED strip.
  
  You will need to connect 5V/Gnd from the Arduino (USB power seems to be sufficient).
  
  For the data pins, please pay attention to the arrow printed on the strip. You will need to connect to
  the end that is the begining of the arrows (data connection)--->
  
  If you have a 4-pin connection:
  Blue = 5V
  Red = SDI
  Green = CKI
  Black = GND
  
  If you have a split 5-pin connection:
  2-pin Red+Black = 5V/GND
  Green = CKI
  Red = SDI
 */
int x;
int SDI = 2; //Red wire (not the red 5V wire!)
int CKI = 3; //Green wire
int ledPin = 13; //On board LED

#define STRIP_LENGTH 32 //32 LEDs on this strip
long strip_colors[STRIP_LENGTH];

You have code for two completely different types of pixels there. What pixels are you using? Please post a link.
We can't help you unless you tell us exactly what pixels you are trying to control.

Hi... Using this pixel in the http://www.adafruit.com/products/1260

the below code you send me that is not working as i send u the error pitcher

please send the code for blink, fade and color change

below code is not working for me

Code: Select all

#define LEDPIN 6;

Adafruit_NeoPixel strip = Adafruit_NeoPixel(1, LEDPIN, NEO_GRB + NEO_KHZ800);


void setup() 
{
  strip.begin();
  strip.show(); // Initialize all pixels to 'off'
}

void loop() 
{
  strip.setPixelColor(0, strip.Color(255,255,255)); // white
  strip.show();
  delay(1000);
  
  strip.setPixelColor(0, strip.Color(0,0,0)); // black
  strip.show();
  delay(1000);
}

Sorry, forgot the calls to "strip.show()"

Code: Select all

#include "Adafruit_FloraPixel.h"

/*****************************************************************************
Example sketch for driving Adafruit Flora pixels
Connect the pixel(s) to Digital 6 (low right hand)
*****************************************************************************/

// Set the first variable to the NUMBER of pixels. 25 = 25 pixels in a row
Adafruit_FloraPixel strip = Adafruit_FloraPixel(8);

void setup() {
    
  strip.begin();

  // Update the strip, to start they are all 'off'
  strip.show();
}


void loop() {
  // Some example procedures showing how to display to the pixels

  Blink(5, 500, Color(255, 255, 255), Color(0,0,0));  // blink white
  Blink(5, 500, Color(255, 0, 0), Color(0,0,0));  // blink red
  Blink(5, 500, Color(0, 255, 0), Color(0,0,0));  // blink green
  Blink(5, 500, Color(0, 0, 255), Color(0,0,0));  // blink blue
  
  Fade(10, Color(255, 255, 255));  // fade white
  Fade(10, Color(255, 0, 0)); // fade red
  Fade(10, Color(0, 255, 0)); // fade green
  Fade(10, Color(0, 0, 255)); // fade blue
}

// alternate between on and off color with delay
void Blink(int count, int ms, RGBPixel on, RGBPixel off)
{
   for (int i = 0; i < count; i++)
   {
      for (int j = 0; j < strip.numPixels(); j++) 
      {
        strip.setPixelColor(j, on);
      }  
      strip.show();
      delay(ms);
      for (int j = 0; j < strip.numPixels(); j++) 
      {
        strip.setPixelColor(j, off);
      }  
      strip.show();
      delay(ms);
   }
}

// fade from start color to black
void Fade(int ms, RGBPixel start)
{
   for (int i = 0; i < 255; i++)
   {
           RGBPixel color = Color(start.red / i, start.green / i, start.blue / i);
      for (int j = 0; j < strip.numPixels(); j++) 
      {
        strip.setPixelColor(j, color);
      }  
      strip.show();
      delay(ms);
   }
}

/* Helper functions */

// Create a 24 bit color value from R,G,B
RGBPixel Color(byte r, byte g, byte b)
{
  RGBPixel p;
  
  p.red = r;
  p.green = g;
  p.blue = b;
  
  return p;
}

Hi... Thanks for the code this is working but can you please let me know how can i control every single pixel. i mean to say is there is 4 pixel and i want to turn on only 1st and 4th then how can i do that can you put any pixel number in this code. this is only doing fade out i want both fade out and fade in.

thanks

The pixel number is the first parameter to setPixelColor. You can specify any pixel number you like.

Just edit the 'for' loop to count down instead of up. http://arduino.cc/en/Reference/for
