Neopixel Water Mood Lamp

a few days ago I was thinking about the lamp and I suddenly realized that water makes the light spread.

so I decided to make a lamp with water.

this project is very simple and easy to make.

Arduino nano

candy can

tube-shaped bottle

Neopixel

you have to connect pin6 to Neopixel IN and 5V to VCC and GND to GND.

fill the water into the bottle and sill with hot glue and thin plastic

and insert it into the can cab.

glue the arduino nano and stick the Nropixel to the bottom of the main lamp.

Assemble are the things you made.

you have to install the Adafruit Neopixel Library in the library manager

and you can find many example codes on the internet.

I used this code

#include <Adafruit_NeoPixel.h>

#define LED_COUNT 6

#define LED_PIN  1

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

void setup() {

 strip.begin();

 strip.show();

 strip.setBrightness(50);

}

void loop() {

 rainbow(10);

}

void rainbow(int wait) {

 for(long firstPixelHue = 0; firstPixelHue < 5*65536; firstPixelHue += 256) {

  for(int i=0; i<strip.numPixels(); i++) { 

   int pixelHue = firstPixelHue + (i * 65536L / strip.numPixels());

   strip.setPixelColor(i, strip.gamma32(strip.ColorHSV(pixelHue)));

  }

  strip.show();

  delay(wait);

 }

}

test the lamp and you can change the code to change the color .
