Step 1: Required Components
Step 2: Connect the RGB Ring to Arduino
Follow the instructions below to connect WS2812 to Arduino Nano :
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
Set the values above according to your needs
After that, upload the sketch to Arduino.
