Configure The Eye

Once you have gone through the HalloWing M4 quick start guide, you'll have the default "blue hazel" eye loaded and displaying. Feel free to customize the settings or graphics! Reference the HalloWing M4 learn guide to explore all the options.

Quick Start

  • Plug in your HalloWing M4 via a known good data+power USB cable.
  • Double press the reset button and wait for the NeoPixels to turn green.
  • The HALLOM4BOOT drive should show up on your computer. 
  • Download the UF2 file below and drop it onto the root of the HALLOM4BOOT drive. 

Touch Input

Use the touch pads to change the NeoPixel animations. There are four different programmed NeoPixel animations. Halloween color gradients, beating heart, breath, and rainbow. These will loop and repeat automatically. 

Building from Source

This project uses a build of the M4 eyes from the Adafruit Learning System GitHub repository (repo). For advanced customization, use the link below to open the section of the Learn guide that walks through setting up Arduino and uploading the code.

Get the code working on the HalloWing M4 before installing into the candy bowl.
