blueprint:
domain: automation
name: Switch scenes with Philips Hue Dimmer Switch (RWL022 or RWL021)
description: >
Control custom scenes within HA in the same way the Hue dimmer switches work for
native Philips Hue scenes. If lights are on then the power button will cycle through
scenes, if they're off it'll try to start the most recently used scene. Off button
will turn off all lights in the most recently used scene's entity list, as will the
brightness up / down control.

Notes on setting up my Raspberry Pi for PiWars, no further explanation but might be helpful!
Install 4.15.9 according to https://www.raspberrypi.org/documentation/linux/kernel/building.md
SSH to pi, then...
sudo apt-get install git bc libdbus-1-dev libglib2.0-dev libudev-dev libical-dev libreadline-dev -y
wget www.kernel.org/pub/linux/bluetooth/bluez-5.49.tar.xz
tar -xvf ./bluez-5.49.tar.xz
cd bluez-5.49/
wget https://gist.github.com/pelwell/c8230c48ea24698527cd/archive/3b07a1eb296862da889609a84f8e10b299b7442d.zip

A bit of code to demonstrate the light strip from insomnialighting.com here - http://www.insomnialighting.com/catalog/index.php?main_page=product_info&cPath=6_4&products_id=8 using an arduino nano. Data and clock lines on the strip are connected to pins 11 and 13 of the nano respectively to make use of hardware SPI.
#include "LPD8806.h"
#include "SPI.h"
// Simple test for 260 (5 meters) of LPD8806-based RGB LED strip, this is a
// modified version of the original demo - it creates a rainbow, animates it
// and fades from black->colours->white->colours->black in a cycle, holding
// somewhat longer on the full colour, all while cycling the rainbow colours.
// This has been tested with a high density (260 LEDs / 5m) strip and a nano
// board, running from a 5V 10A PSU.
