Lamp with WS2812B led

Last crawled date: 5 years, 10 months ago

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:

#include

#define NUM_LEDS 39
#define BRIGHTNESS 170

CRGB leds[NUM_LEDS];

void setup() {
delay( 3000 ); // power-up safety delay
FastLED.addLeds(leds, 0, 13); //Pin 3, LED 0 to 13
FastLED.addLeds(leds, 13, 26); //Pin 5, LED 13 to 26
FastLED.addLeds(leds, 26, 39); //Pin 7, LED 26 to 39
FastLED.setBrightness( BRIGHTNESS );
}

randomSeed(millis());

rainbow(wait);
}

void rainbow(uint8_t wait) {
uint16_t i, j;

for(j=0; j<256; j++) {
for(i=0; i CRGB ledColor = wheel((i*1+j) & 255);
leds[i]=ledColor;
}
FastLED.show();
FastLED.delay(wait);
}
