Welcome to our Neopixel wiki by Einstein

What do we use for this project

• Neopixel Ledstrip WS2812 60leds/mtr
• Controlerboard
  • Arduino Ethernet (ready for networking features :))
  • STM

Other stuff you might need

• Networkcable
• USB cable
• Powersupply

Control your Neopixel Leds

Arduino

Connecting

Hardware

• Connect your Neopixel LED strip DI to pin6 of your Arduino
• Connect +5V and GND to your Arduino

Software

• #define NUM_LIGHTS 4 //Number off connected leds (i use 4 in all sources, please change to 60 for 1 meter)
• #define PIN 6 //Pin 6 for Data

Programming

Software

Arduino Software

Arduino Software can be downloaded here -> http://arduino.cc/en/Main/Software

Examples

Example by Adafruit

• Adafruit Neopixel example to get you going https://raw.github.com/adafruit/Adafruit_NeoPixel/master/examples/strandtest/strandtest.pde

Examples by Einstein

• Simple ON in one color

   File:Neopixel_all_on.ino.txt

• Simple OFF in one color

   File:Neopixel_all_off.ino.txt

• Using colorcodes.h instead of rgb values

Using colorcodes.h instead of rgb values in code, because i got tired of typing numbers :)

• • use this file and include it in the source

   File:colorcodes.h.txt

• • already changed sources

   Sample ON:

   Sample OFF:
   File:Neopixel_all_low_colorcodes.ino.txt

• Simple blink in one color
