	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

tomoinn / rainbow_strip.cc

Created July 10, 2013 18:49

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.
