you cannot power more than about a dozen pixels with conductive thread. for more, you need to use wire, 22AWG stranded or thicker is best.

If one pixel stops working because it does not have poewr or the data isnt valid, ALL pixels after it will not work anymore.

we suggest powering with 6VDC since there is a lot of pixels, the heat dissipation would be too much otherwise. 4xAA batteries is ideal.

you should start with a simple project, with 8 or 16 pixels to start, to get a hang of how to use them

What range do you need for the remote control?

Around 50 to 100 meter range ?

For that kind of range, I would recommend XBee modules. The basic model is rated for up to 100 meters, but that is assuming ideal conditions. For better reliability, I would suggest the XBee Pro which has a much longer range. - http://www.adafruit.com/products/964

The ones we sell meet FCC requirements for use in the US. Radio frequency regulations may be different in your country. Digi.com is the manufacturer of these modules and they make models to meet regulations in many different countries. http://www.digi.com/products/xbee/

The library for the WS2811 neopixel strips is here: https://github.com/adafruit/Adafruit_NeoPixel

These are simple to connect. They need power, ground and one digital pin. The digital pin is specified in the constructor. The example code uses pin 6:

Code: Select all

#include <Adafruit_NeoPixel.h>

#define PIN 6

// Parameter 1 = number of pixels in strip
// Parameter 2 = pin number (most are valid)
// Parameter 3 = pixel type flags, add together as needed:
//   NEO_RGB     Pixels are wired for RGB bitstream
//   NEO_GRB     Pixels are wired for GRB bitstream
//   NEO_KHZ400  400 KHz bitstream (e.g. FLORA pixels)
//   NEO_KHZ800  800 KHz bitstream (e.g. High Density LED strip)
Adafruit_NeoPixel strip = Adafruit_NeoPixel(60, PIN, NEO_GRB + NEO_KHZ800);

Hi Dear sorry to bother you again

Can you please let me know how much max pixel gemma and trincket can run

can you please help to add fade in and fade out code in the same format below code

and also let me know the code to make full strip on and off

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(100);

void setup() {
    
  strip.begin();

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

  int x;
  
void loop() {
  
 
  strip.setPixelColor(0, 0, 0, 255); // Blue
  strip.show();
  delay(500);
  strip.setPixelColor(0, 0, 0, 0); // Blue
  strip.show();
  delay(500);
}
