Neopixel RGB LED 5-Color Cycler (Arduino)

This project is a ring of 12 RGB LEDs controlled to show different set colours (in a smile pattern), based on the resistance of the slide potentiometer.

If anyone has any suggestions, I'd be happy to read them as improvements can always be made. :)

Step 1: Bill of Materials (BOM)

• Any Arduino board or Arduino IDE compatible configuration (ex. an ATMEL IC w/the necessary components)
  
  Arduino UNO R3 I used:
  • ARDUINO UNO REV3
    
    
• Breadboard or PCB
  
  The breadboard I used:
  

  • Full Sized Breadboard (Adafruit)
    Full Sized Breadboard (Aliexpress)

• Any size RGB LED Ring or "Adafruit NeoPixel Ring"
  
  RGB LED Ring I used with 12 LEDs:
  • Adafruit NeoPixel Ring
  • RGB 12 LED Ring (Aliexpress)
• A potentiometer/variable resistor (preferably 10k ohms for precision)
  
  Potentiometer I used:
  • Slide Potentiometer 10K (Aliexpress)
    
• About about 10 Jumper Wires (Male-Female/Male-Male/Female-Female type and quantity depending on chosen configuration)
  
  Jumper wires I used:
  • Male/Male Jumper Wires (Adafruit)
  • Male-Male 20cm Dupont/Jumper Cable (Aliexpress)

Step 2: Wiring

Step 3: Arduino Code

The original code is an Adafruit Neopixel Example, "Simple," modified by myself to work with this project.
Currently it shows five different colours, either red, yellow, green, blue or violet. If the potentiometer is not in range of the values set into the conditional statements, it will turn all the LEDs off. (set R,G,B to 0,0,0).
