Simple Arduino NeoPixel Sketch

I found the Adafruit  NeoPixel  Arduino examples rather over complicated for the beginner . So I wrote a simple sketch which does nothing more that produce Red, Green and Blue on 3 separate pixels. 

/*

#include <Adafruit_NeoPixel.h>

// State which pin is used on the arduino?
#define PIN            6

// Total Number of Pixels
#define NUMofPIXELS      16

// setup the NeoPixel library, number of pixels and pin .
Adafruit_NeoPixel pixels = Adafruit_NeoPixel(NUMofPIXELS, PIN, NEO_GRB + NEO_KHZ800);

void setup() {
pixels.setBrightness(255); // Global Brightness
  pixels.begin(); // initializes the NeoPixel library.
}

void loop() {
    // pixels.Color takes RGB values, from 0,0,0 up to 255,255,255
    // pixels.setPixelColor(Pixel number "0" is the first, red, green, blue);
     // http://www.rapidtables.com/web/color/RGB_Color.htm
     
   pixels.setPixelColor(0,pixels.Color(255,0,0)); // RED
   pixels.setPixelColor(1,pixels.Color(0,255,0)); // GREEN
   pixels.setPixelColor(2,pixels.Color(0,0,255)); // BLUE

   
    pixels.show(); //  sends the value, when the color has been set
}

Hakko FX-888D DIN Connector Pinouts


While making some modifications to my Hakko FX-888D, I found if necessary to note down the pinouts for the FX-8801 soldering iron plug, and the 6 pin DIN socket on the 888D. I could not find much information on Google, so decided to post my findings, as it may be useful to others.

Adafruit NeoPixel Ring 3D Sketchup Models


Just a quick post to share my Adafruit  NeoPixel ring 3D Sketchup  models :)

Available to download on the Project Design Files page.

On a side note Tim's Blog has some nice information regarding clones of the WS2812 series RGB LEDS, including their respective timings, you can read more on the subject on his blog here.
