Simple NeoPixel Animation for Arduino on WeMos D1 Mini, License: MIT

neopixel.ino

#include <Adafruit_NeoPixel.h>

#define NUM_PIXELS 24

Adafruit_NeoPixel pixels(NUM_PIXELS, D2, NEO_GRB | NEO_KHZ800);

void setup() {
  pixels.begin();
}

void setColor(uint32_t color) {
  for (int i = 0; i < NUM_PIXELS; i++) {
    pixels.setPixelColor(i, color);
    pixels.show();
    delay(50);
  }
}

void loop() {
  setColor(pixels.Color(100, 0, 0));
  delay(1000);
  setColor(pixels.Color(0, 100, 0));
  delay(1000);
  setColor(pixels.Color(0, 0, 100));
  delay(1000);
}

If this is for an ESP, isn't the delay function a bad idea? This should use a timer and millis, and there is a lib called simple timer that makes it easy. If you use delay with wifi functions, it can lose the wifi connection.

Hi, Need help.....! I am unisg WeMos D1R2 and WS2812B Led Lights. I had use your code but nothing happening. Can you please help.
