Neopixels_on_esp8266_with_Blynk (1).ino

Arduino
/*code written by Struan Lawrie
 * with parts taken from strandtest example for neopixels and blynk examples
 * 
 * WIRING:
 * NodeMCU or any other esp8266 module
 * GND of neopixels to MCU GND
 * DATA of neopixels to MCU pin D3
 * +5V of Neopixels to SEPERATE 5V POWER SUPPLY!!! otherwise neopixels draw too much current and
 * fry the esp8266
 * connect power supply GND to MCU GND

// Parameter 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)
Adafruit_NeoPixel strip = Adafruit_NeoPixel(numberOfNeopixels, PIN, NEO_GRB + NEO_KHZ800);

// IMPORTANT: To reduce NeoPixel burnout risk, add 1000 uF capacitor across
// pixel power leads, add 300 - 500 Ohm resistor on first pixel's data input
// and minimize distance between Arduino and first pixel.  Avoid connecting
// on a live circuit...if you must, connect GND first.
