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.

// NeoPixel test program showing use of the WHITE channel for RGBW
// pixels only (won't look correct on regular RGB NeoPixel strip1s).

#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_PINR 3
#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
// Declare our NeoPixel strip1 object:
Adafruit_NeoPixel strip1=Adafruit_NeoPixel(LED_COUNT, LED_PINR, NEO_GRBW + NEO_KHZ800);
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)
