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

Re: Flora Coding
Hi.. i want to turn arduino uno on and off by remote. i want 1 remote for 10 to 15 receivers turn them on and off at the same time.
please let me know how i can do that and how i can connect the receiver to arduino board ?

Re: Flora Coding
What range do you need for the remote control?

Re: Flora Coding
Around 50 to 100 meter range ?

Re: Flora Coding
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

Re: Flora Coding
ok thanks i will try xbee. i also want to know the code to run ws2811 strip from arduino and also want to know the how to connect ws2811 strip to arduino

Re: Flora Coding
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:
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);

Re: Flora Coding
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
