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

Adafruit Neopixel libraries

Adafruit Neopixel libraries can be downloaded here -> libraries https://github.com/adafruit/Adafruit_NeoPixel

Examples

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, rename to colorcodes.h
   File:colorcodes.h.txt
    • Already changed ON/OFF sources
   Sample ON:
   File:Neopixel_all_on_colorcodes.ino.txt
   
   Sample OFF:
   File:Neopixel_all_low_colorcodes.ino.txt
  • Simple blink in one color

STM

Connecting

Hardware

  • Connect your Neopixel LED strip DI to pin6 of your STM
