Neopixel Christmas Lights

Schematic diagram

Parts used in the diagram

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...
