Arduino Uno Based RGB Ring Control By Using Rotary Encoder
To create an Arduino Uno-based RGB ring control using a rotary encoder, you'll need the following components:
- Arduino Uno
- RGB LED Ring
- Rotary Encoder
- Resistors (for the encoder)
- Jumper wires
Here's a basic connection diagram and example Arduino code to get you started:
Connection Diagram:
Connect the components as follows:
- Connect the CLK (clock) pin of the rotary encoder to digital pin 2 on the Arduino.
- Connect the DT (data) pin of the rotary encoder to digital pin 3 on the Arduino.
- Connect the SW (switch) pin of the rotary encoder to digital pin 4 on the Arduino.
- Connect the common ground of the rotary encoder to the ground (GND) pin on the Arduino.
- Connect the VCC pin of the rotary encoder to the 5V pin on the Arduino.
- Connect the RGB LED Ring to the Arduino:
- Connect the data pin of the RGB LED Ring to a PWM-enabled digital pin (e.g., 9) on the Arduino.
- Connect the VCC pin of the RGB LED Ring to the 5V pin on the Arduino.
- Connect the GND pin of the RGB LED Ring to the ground (GND) pin on the Arduino.

Additional Notes:
- Make sure to install the Adafruit Neo Pixel library in the Arduino IDE to run this code.
- Adjust the NEOPIXEL_COUNT variable based on the number of LEDs in your RGB LED Ring.
- The code uses a simple color wipe effect, and you can modify it based on your preferred lighting effects or color schemes.
- Customize the code to add additional features such as brightness control or switch press actions.
- This code provides a starting point for controlling an RGB LED Ring using a rotary encoder with an Arduino Uno.
- Adjustments and enhancements can be made based on your specific project requirements.
