Neopixel LED Face Mask

splat238 shared this pretty awesome LED face mask. If you’re thinking about making your own, this one looks pretty awesome!

The mask uses 104 WS2812b LEDs, assembled from sections of commonly available 144 LEDs/m LED strip. WS2812b’s are individually addressable, meaning that you control the color of each led. This lets you create almost any effect you can imagine (as long as you can code it). If you’re not sure what effects you might like, or don’t want to write a bunch of code, don’t worry; I’ve written code to control the mask, including 41 different effects, which you can control using a series of buttons. The LEDs are controlled using a Wemos D1 Mini, an Arduino compatible micro-controller featuring an ESP8266 as the processor. This gives you plenty of memory and power to run as many effects as you’d like. It also gives you access to WiFi functionality (although not currently implemented in my code). The mask is powered externally via a 1S LiPo cell. Although the mask can run for a long time on just one cell, by keeping the cell external, you can easily swap in a fresh one. The all the components are mounted on custom PCB’s (except the LED strip).

8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
