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

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

Examples

Example by Adafruit
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:
   File:Neopixel_all_on_colorcodes.ino.txt
   
   Sample OFF:
   File:Neopixel_all_low_colorcodes.ino.txt
  • Simple blink in one color
