How to Change Color on Neopixel Lightsaber: A Step-by-Step Guide

You know that your lightsabers are more than just props—they're the pulsating heart of your cosplay persona. And guess what? With Neopixel technology, these iconic weapons have evolved, meaning you have the power to command a wide range of colours at your fingertips.

Understanding Neopixel Technology

Before we get started, let’s understand how Neopixel lightsabers work. Neopixel LEDs are individually addressable RGB (Red, Green, Blue) LEDs that allow for precise control over each light element. Unlike traditional lightsabers with single-color LEDs, Neopixel sabers can produce a multitude of colors and effects, making them highly customizable (and absolutely epic-looking!)

Tools and Materials Needed

To change the color on your Neopixel lightsaber, here’s what you’ll need:

  • Neopixel lightsaber with compatible controller (such as a Proffieboard or CFX)
  • Computer with appropriate software installed (e.g., Arduino IDE for Proffieboard)
  • USB cable for connecting the lightsaber to your computer
  • Access to color configuration files or code (varies depending on the saber’s controller)

Step-by-Step Guide

  1. Connect Your Lightsaber to Your Computer: Using the USB cable, connect your Neopixel lightsaber to your computer. Ensure that the appropriate drivers are installed and that your computer recognizes the device.
  2. Access the Configuration Files or Code: Depending on the controller used in your lightsaber, you’ll need to access the configuration files or code to change the color. For example, if you’re using a Proffieboard, you’ll need to open the Arduino IDE and load the configuration file for your lightsaber.
  3. Locate the Color Settings: Within the configuration files or code, locate the section that controls the color settings. This may be labeled as “blade settings” or something similar. Depending on the controller, you may have the option to specify a single color or create color profiles with multiple colors and effects.
  4. Adjust the Color Values: Once you’ve located the color settings, you can begin adjusting the RGB values to achieve your desired color. Experiment with different combinations to create unique hues and effects. Some controllers may also offer presets or color palettes to choose from.
  5. Upload the Changes: After you’ve customized the color settings to your liking, save the changes and upload them to your lightsaber’s controller. This process may vary depending on the software and controller used. Follow the instructions provided by the manufacturer or community guides for your specific setup.
  6. Test Your Lightsaber: Once the changes have been uploaded, disconnect your lightsaber from the computer and power it on. Test the color changes to ensure they appear as intended. Make any additional adjustments as needed until you’re satisfied with the results.
  7. Go forth with the Force: You’re ready to turn heads and take on your next epic journey!


With Neopixel technology, changing the color of your lightsaber has never been easier. By following this step-by-step guide, you can unleash your creativity and personalize your lightsaber to reflect your unique style and personality. Whether you’re a Jedi, Sith, or somewhere in between, the ability to customize your lightsaber’s color adds an extra layer of immersion and excitement to your Star Wars experience. May the Force be with you as you embark on your color-changing journey!
