Tutorial: How to Use WS2812 LED Ring

The RGB WS2812 LED ring is ideal for lighting and color visualization projects. Perfect for beginners and intermediates.

What you need

• Arduino
• USB cable
• Arduino IDE software

Steps

1. 1. Download and install the Arduino IDE.
2. 2. Connect the LED ring to the Arduino via the following pins: VCC to 5V, GND to GND, DATA to a digital pin.
3. 3. Open a new sketch in the Arduino IDE.
4. 4. Enter the following code: `#include
   #define PIN 6
   Adafruit_NeoPixel pixels(16, PIN, NEO_GRB + NEO_KHZ800);
   void setup() {
   pixels.begin();
   }
   void loop() {
   pixels.setPixelColor(0, pixels.Color(255, 0, 0));
   pixels.show();
   delay(1000);
   pixels.setPixelColor(0, pixels.Color(0, 255, 0));
   pixels.show();
   delay(1000);
   pixels.setPixelColor(0, pixels.Color(0, 0, 255));
   pixels.show();
   delay(1000);
   }`
5. 5. Compile and upload the code to the Arduino.
6. 6. Check that the LED ring changes color as expected.
7. 7. Try modifying the code to create custom effects.
8. 8. Check the datasheet for further settings.

Example code

```
#include <Adafruit_NeoPixel.h>
#define PIN 6
Adafruit_NeoPixel pixels(16, PIN, NEO_GRB + NEO_KHZ800);
void setup() {
  pixels.begin();
}
void loop() {
  pixels.setPixelColor(0, pixels.Color(255, 0, 0));
  pixels.show();
  delay(1000);
  pixels.setPixelColor(0, pixels.Color(0, 255, 0));
  pixels.show();
  delay(1000);
  pixels.setPixelColor(0, pixels.Color(0, 0, 255));
  pixels.show();
  delay(1000);
}
```

Mini project
