Sending float array through I2C from Arduino to RPi

	#include <Wire.h>

	#define SLAVE_ADDRESS 0x04
	#define FLOATS_SENT 3

	float data[FLOATS_SENT];

	void setup() {
	pinMode(13, OUTPUT);
	Serial.begin(9600); // start serial for output

Ambilight for Arduino

	#include "FastLED.h"

	// How many leds in your strip?
	#define NUM_LEDS 248

	// For led chips like Neopixels, which have a data line, ground, and power, you just
	// need to define DATA_PIN. For led chipsets that are SPI based (four wires - data, clock,
	// ground, and power), like the LPD8806 define both DATA_PIN and CLOCK_PIN
	#define DATA_PIN 5
	//#define CLOCK_PIN 13
