Neopixel Christmas Lights

Schematic diagram

./img/scheme.png

Parts used in the diagram

./img/parts.png

From left to right these parts are:

  • 470Ω resistor
  • 10kΩ resistor
  • 100nF ceramic capacitor
    • These are not polarized and you can connect them in any way
  • 1000uF/6.3V capacitor
    • The short leg is minus. Sometimes there is a minus sign one the negative side as well
  • NeoPixel 5mm Through-Hole LED. The legs from left to right represent (the flat side is to the right):
    • Short leg 1: Data in
    • Short leg 2: +5V
    • Long leg 1: Ground
    • Long leg 2: Data out
  • A push button

How to compile

Download the arduino IDE. Install the following libraries (other versions than the ones given will most probably work as well but I compiled it with these versions):

  • Adafruit NeoPixel version 1.1.3
  • EnableInterrupt version 0.9.8

To install a library go to Sketch -> Include Library -> Manage Libraries...
