I'm attempting to fade a strip of ws2812 7 pixels in length. Below I am using a for loop to increment the color red. I can fade it to red (from blue) but it will do it one pixel at a time or it just stays blue, depending where I move my r for-loop to. I need it to fade from color to color all 7 LEDs at once.
I get no errors.
I don't understand the process of getting NUM_LEDS leds all into x then proceeding with my color changing. Seems like I'm grabbing one pixel, fading it to red, then another...
fastLeds 3.03 library, arduino 1.0.6
#include <FastLED.h>
#define DATA_PIN 6
#define NUM_LEDS 7
#define BRIGHTNESS 45
#define COLOR_ORDER GRB
#define g 50
#define b 100
int r;
CRGB leds[NUM_LEDS];
void setup(){
FastLED.addLeds<WS2811, DATA_PIN, GRB>(leds, NUM_LEDS);
}
void loop(){
for(int x = 0; x < NUM_LEDS; x++){
delay(10);
leds[x] = CRGB(r,g,b);
}
FastLED.show();
delay(10);
//-------------------------
for(int x = 0; x < NUM_LEDS; x++){
for(int r = 0; r < 254; r++) {
if NUM_LEDS is holding the number 7 why cant ican't I just do it like this below: leds[NUM_LEDS]?
leds[x] = CRGB(r,g,b);
FastLED.show();
delay(100);
}
}
}
}
