WS2812 to Arduino

IN ==> D6

VCC ==> +5V

GND ==> GND

Step 3: Programing

Open Arduino IDE

Click File > Examples > Adafruit NeoPixel > strandtest

You must change some values from this sketch,

What must be changed is as follows:

  • Pin used
#define LED_PIN    6
  • Number of LEDs
#define LED_COUNT 16
  • Set Brightness
strip.setBrightness(10);

Set the values above according to your needs

After that, upload the sketch to Arduino.
