This Arduino-powered LED matrix mask responds to your voice

When wearing a face mask nowadays, you can’t show expressions in the same ways that we’re all accustomed to. As a possible solution to this problem, programmer Tyler Glaiel decided to create a custom covering, with an 8×8 LED matrix that picks up his voice and imitates his mouth moving. It even allows him to smile by sensing when he makes a “pop” sound.

The build is entirely self-contained, with an Arduino Nano, 9V power supply, and electret microphone embedded in the mask’s translucent black cloth.

Instructions on how to make your own are available in Glaiel’s blog post, though he is quick to note that it’s not guaranteed to inhibit virus transmissions, and is meant as something of a novelty.
