// LED STRIP EXAMPLE
// can use this to write code at home

// -----------------------------------------

// use the FastLED library (someone's pre-written code)
#include <FastLED.h>

// set how many LEDs there are and the data pin.
const int NUM_LEDS = 30;
const int DATA_PIN = 6;

// this creates an array to reference our LEDs
CRGB leds[NUM_LEDS];

void setup() {
  // tells the FastLED code e.g. what LEDs we are using, the data pin
  FastLED.addLeds<NEOPIXEL, DATA_PIN>(leds, NUM_LEDS);
  
  // limit the strip's draw to 400mA at 5v 
  FastLED.setMaxPowerInVoltsAndMilliamps(5,400);
  
  // turns the brightness down (so my eyes don't hurt)
  FastLED.setBrightness(8);
}

void loop() {
  // Example code from Tutorial 7
  for (int light=0; light<30; light++) {
    leds[light] = CRGB::CRGB::Coral;
    FastLED.show(); 
  delay(100);
  }

  for (int light=0; light<30; light++) {
    leds[light] = CRGB::Black;
  }
  FastLED.show(); 
  delay(1000);
