Spooky eyes - halloween Eyes assembly with schematic and configuration

This is my version of a project I saw mentioned on a forum site. It is originally by Adafruit, and also reworked by Sudomod.

The video shows the hardware assembly from packaged parts to a working pair of "eyes".

The schematic diagram and the config file, adapted to work with the Seeed Xiao and that schematic, are here:

I must stress that the concept and brilliant software to display the numerous eye variations are all their work and the original articles etc, are linked below.

My version uses a different microcontroller module to the ones mentioned in those articles, which appears to be cheaper and easier to find at present, a Seeed Studios XIAO which uses the same CPU as the Aruinos mentioned in the other project articles, so only needs the appropriate library installing in the Arduino IDE to be fully usable.

Edit - Be sure to get the Xiao version with the SAMD21 (ARM M0) MCU - Since I made the video, Seeed have released other Xiao modules with different ICs / CPU types, which may not work or may require different program settings - I do not have any to try.

The video thumbnail shows the pair built during the video, stuck in to a plastic skull with strips of tape across the back of the displays, plus another pair unmounted.

For the software side, see the original projects and software from these links:-

And the program ("sketch") for their version:

Sudomod's variation, which moves each eye independently, allowing two display in parallel on each channel, so two pairs of eyes using one MCU :

Update - apparently some people have had problems with the links to the original files; a full project file with my config is here:

And for the Seeed MCU I used, their Wiki page with details on the device and instructions for adding their library to the Arduino IDE; see the section headed Software, about half way down the page:

The plastic skull used in the video was from a high street shop, "Wilco" I believe.
The robot face section is a 3D printed part from Gael Langevin's "Inmoov" robot design:
