Lamp with WS2812B led

thingiverse

Lamp i design with three strips of WS2812B leds. Total 39 leds and a Arduino Nano to control the light. Adafruit effect aka FastLED Please note I am not a programmer so I am in no way saying this is properly made. But this code works for me :) Source code: (https://gofile.io/?c=ZmQHGg) <pre><code>#include &lt;FastLED.h&gt; #define NUM_LEDS 39 #define BRIGHTNESS 170 CRGB leds[NUM_LEDS]; void setup() { delay( 3000 ); // power-up safety delay FastLED.addLeds&lt;WS2812B, 3, GRB&gt;(leds, 0, 13); //Pin 3, LED 0 to 13 FastLED.addLeds&lt;WS2812B, 5, GRB&gt;(leds, 13, 26); //Pin 5, LED 13 to 26 FastLED.addLeds&lt;WS2812B, 7, GRB&gt;(leds, 26, 39); //Pin 7, LED 26 to 39 FastLED.setBrightness( BRIGHTNESS ); } void loop() { randomSeed(millis()); int wait=30; rainbow(wait); } void rainbow(uint8_t wait) { uint16_t i, j; for(j=0; j&lt;256; j++) { for(i=0; i&lt;NUM_LEDS; i++) { CRGB ledColor = wheel((i*1+j) &amp; 255); leds[i]=ledColor; } FastLED.show(); FastLED.delay(wait); } } CRGB wheel(byte WheelPos) { CRGB color; if (WheelPos &lt; 85) { color.r = WheelPos * 3; color.g = 255 - WheelPos * 3; color.b = 0; } else if (WheelPos &lt; 170) { WheelPos -= 85; color.r = 255 - WheelPos * 3; color.g = 0; color.b = WheelPos * 3; } else { WheelPos -= 170; color.r = 0; color.g = WheelPos * 3; color.b = 255 - WheelPos * 3; } return color; }</code></pre>
