StripHSV

Rainbeau test sketch for strip of addressable RGB LEDs.

Requires http://fastled.io/ library.

#include "FastLED.h"

// How many leds in your strip?
#define NUM_LEDS 12

// Spacing between pixel/color
#define HSV_PAD 22

// Delay between cycles
#define LOOP_DELAY 20

// 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 11
// #define CLOCK_PIN 13

// Define the array of leds
CRGB leds[NUM_LEDS];

byte count = 0;

void setup() { 
      // Uncomment/edit one of the following lines for your leds arrangement.
      FastLED.addLeds<WS2812B, DATA_PIN, RGB>(leds, NUM_LEDS);
