This add-on is supported for MATLAB R2019a or higher.
.
This add-on library extends MATLAB Support Package for Arduino Hardware to control Adafruit NeoPixel LED strip. With this add-on, you can control the color and brightness of an RGB or RGBW NeoPixel strip to produce various lighting effects.
Sample usage:
Create arduino object with the add-on library
a = arduino('COM10', 'Uno', 'Libraries', 'Adafruit/NeoPixel');
Create NeoPixel strip object with 30 pixels
sensor = addon(a, 'Adafruit/NeoPixel', 'D6', 30);
Write colors to the first 20 pixels
writeColor(neostrip, 1:10, 'magenta', 11:20, 'yellow');
It includes the documentation and examples that demonstrate the use of the Adafruit NeoPixel addon.
Important: Before using this add-on library in MATLAB, you need to install the Adafruit NeoPixel Arduino library. Here are the instructions:
Installation:
  1. Download the zip file from https://github.com/adafruit/Adafruit_NeoPixel/archive/v1.1.2.zip
  2. Unpackage the zip into local directory and rename the folder to ‘Adafruit_NeoPixel'.
  3. Move the ‘Adafruit_NeoPixel’ folder into the "libraries" folder inside your Arduino sketchbook folder:
For R2019a:
  • On Windows®, the default path is "Documents\Arduino\libraries\"
  • On Mac®, the default path is "~/Documents/Arduino/libraries/"
  • On Linux®, the default path is "/home/<username>/Arduino/libraries"
For R2019b and later:
  • On Windows®, the default path is "Arduino IDE Path\portable\sketchbook\libraries\"
  • On Mac®, the default path is "~/Documents/Arduino/libraries/"
  • On Linux®, the default path is "Arduino IDE Path/portable/sketchbook/libraries/"
Note: Arduino IDE Path is returned by the following command in the MATLAB Command Window
arduinoio.IDERoot
For R2024a and later, across all operating systems, the library location can be determined by executing the following command:
fullfile(arduinoio.CLIRoot, 'user','libraries')
Troubleshooting tips:
  1. After installing this add-on library and the required Arduino library, type "listArduinoLibraries" in MATLAB to see if the add-on is properly installed.
  2. Wire up the Arduino board and the add-on device properly before creating the object to avoid a connection error in MATLAB.
  3. Refer to the documentation for details on usage and syntax. It can be found under Supplemental Software in the product documentation.
