Arduino - LED

/*

Blink

Turns an LED on for ten seconds, print to Serial Console, then off for one second, repeatedly.

Most Arduinos have an on-board LED you can control. LED_BUILTIN is set to

the correct LED pin independent of which board is used.

This example code is in the public domain.

// A basic everyday NeoPixel strip test program.

// NEOPIXEL BEST PRACTICES for most reliable operation:

// - Add 1000 uF CAPACITOR between NeoPixel strip's + and - connections.

// - MINIMIZE WIRING LENGTH between microcontroller board and first pixel.

// - NeoPixel strip's DATA-IN should pass through a 300-500 OHM RESISTOR.

// - AVOID connecting NeoPixels on a LIVE CIRCUIT. If you must, ALWAYS

// connect GROUND (-) first, then +, then data.

// - When using a 3.3V microcontroller with a 5V-powered NeoPixel strip,

// a LOGIC-LEVEL CONVERTER on the data line is STRONGLY RECOMMENDED.

// (Skipping these may work OK on your workbench but can fail in the field)

#include <Adafruit_NeoPixel.h>

#ifdef __AVR__

#include <avr/power.h> // Required for 16 MHz Adafruit Trinket

#endif

// Which pin on the Arduino is connected to the NeoPixels?

// On a Trinket or Gemma we suggest changing this to 1:

#define LED_PIN 6

// How many NeoPixels are attached to the Arduino?

#define LED_COUNT 60

// Declare our NeoPixel strip object:

Adafruit_NeoPixel strip(LED_COUNT, LED_PIN, NEO_GRB + NEO_KHZ800);

// Argument 1 = Number of pixels in NeoPixel strip

// Argument 2 = Arduino pin number (most are valid)

// Argument 3 = Pixel type flags, add together as needed:

// NEO_KHZ800 800 KHz bitstream (most NeoPixel products w/WS2812 LEDs)

// NEO_KHZ400 400 KHz (classic 'v1' (not v2) FLORA pixels, WS2811 drivers)

// NEO_GRB Pixels are wired for GRB bitstream (most NeoPixel products)

// NEO_RGB Pixels are wired for RGB bitstream (v1 FLORA pixels, not v2)

// NEO_RGBW Pixels are wired for RGBW bitstream (NeoPixel RGBW products)

// setup() function -- runs once at startup --------------------------------

// Any other board, you can remove this part (but no harm leaving it):
