Welcome to our Neopixel wiki

What do we use for this project

• Neopixel Ledstrip WS2812 60leds/mtr
• Controlerboard
  • Arduino Ethernet (ready for networking features :))
  • STM32F4Discovery
  • Cubieboard2

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 transfer

Programming

Software

Arduino Software

• Arduino Software Windows/Linux/Mac

Examples by Einstein

• Simple OFF in one color (black)
  • File:Neopixel_all_off.ino.txt

• Simple ON in one color (white)
  • File:Neopixel_all_on.ino.txt

• Using colorcodes.h instead of rgb values in code, because i got tired of typing numbers :) download colorcodes.h and include it in the source, rename to colorcodes.h
  • File:colorcodes.h.txt

• Sample OFF with colorcodes (black)
  • File:Neopixel_all_off_colorcodes.ino.txt

• Sample ON with colorcodes (white)
  • File:Neopixel_all_on_colorcodes.ino.txt

• Simple blink/strobe light in one color
  • File:Neopixel_Strobe.ino.txt

STM32F4Discovery

Connecting

Hardware

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

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
