The Pixel Mask animates mouth movements for fun yet safe trick-or-treating

Arduino TeamOctober 7th, 2020

While trick-or-treating may or may not be in effect this Halloween, if you’re planning to participate, a mask could be a good idea. To help add some “expression” to your COVID-19 facial covering, BuildXYZ has come up with the Pixel Mask — capable of showing fangs and other graphics on an 128×64 OLED screen to match any costume.

But that’s not all. The device is equipped with an Arduino Nano and microphone that senses sound levels and then animates a mouth on the front display to mimic a wearer’s mouth movements. There’s even a button to activate a special “Trick or Treat” message.

The build can be equipped with N95 filter material, and is powered by a portable USB pack. Print files are available on Thingiverse and code is on GitHub if you’d like to construct your own.
