Amazing RGB LED Table Lamp
Hello friends, this is very cool project using RGB LED strip and glue stick. New look RGB light will provide you good look on your table. In this projects I used WS2812 addressable RGB LED, so it is very simple to handle Colors on this light.

// Which pin on the Arduino is connected to the NeoPixels?
// On a Trinket or Gemma we suggest changing this to 1:

#define LED_PINL 4
// How many NeoPixels are attached to the Arduino?
#define LED_COUNT 10
// NeoPixel brightness, 0 (min) to 255 (max)
#define BRIGHTNESS 50

Adafruit_NeoPixel strip2=Adafruit_NeoPixel(LED_COUNT, LED_PINL, NEO_GRBW + NEO_KHZ800);
// Argument 1 = Number of pixels in NeoPixel strip1
// 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)
