LittlevGL is a nice open source graphics library for generating graphical user interfaces (buttons, sliders, graphs and so forth) on microcontrollers. We’ve made an Arduino library that simplifies the task of sticking LittlevGL on many Adafruit displays (including touchscreens): PyPortal, TFT FeatherWings, and most other Adafruit devices using a color TFT or OLED screen.

I adore most anything with LEDs, but found those store-bought icicle or meteor lights a bit lacking. Nature rarely moves in straight lines and perfect intervals! In this project we’ll make our own, applying some basic physics for an eye-catching drip effect. PLUS…these have a built-in magic trick, making a “splat” where they hit the ground!

Ready-made eyes for Circuit Playground Bluefruit and Express with the TFT Gizmo display. These install quickly and easily thanks to these boards’ UF2 bootloader. If you need to customize with different graphics or finer control, look for the original “Electronic Animated Eyes” guide and compile from the source code.

Blood! Ectoplasm! Dripping, weeping buboes! NeoPixels and math team up to create a gruesome illusion…this oozing prop is a completely DRY effect!

Create a furry puppet that's reminiscent of Fizzgig from the Dark Crystal movie. Give him lifelike eyes with an Adafruit Monster M4sk and an animated mouth with an adorable bark. He's a perfect guard for your Halloween candy, or he makes a great purse pet or costume accessory.

Got an ADABOX 013 or a MONSTER M4SK board and wondering what to do next? Some collected thoughts on using the board’s animation and sound to liven up a costume.

“Augmented reality” normally involves computer graphics overlaid on what you see. But what if we turned this around and instead changed how you’re seen? Let’s use the Adafruit MONSTER M4SK and the “Pepper’s ghost” illusion to put new eyes on your own face.

A few methods are presented for readying photos and artwork for E-Ink displays that work with CircuitPython and Arduino.

Our Trellis Feather Acrylic Enclosure is such a dense little package that we put together this guide to help with assembling it.

Our easiest animated eyes yet! No programming required…place graphics on a flash drive and edit a text file to customize everything.

What makes the original Speak & Spell voice so distinctly Speak & Spell is that it’s one actual specific person’s voice, not a piecing-together of synthetic phonemes. It then picks up an additional thick “technological accent” through the heavy processing of LPC encoding, storage and reconstruction.

Use your little-screen Adafruit PyGamer or PyBadge to control big-screen games on your computer or game console — anything that works with a USB keyboard.

In the pantheon of corny gags — rubber chickens, whoopee cushions and so forth — there’s a special place for googly eyes, that staple of childrens crafts and tacky “You’re HOW old?” birthday cards.

The Adafruit HalloWing ships with a spooky eyeball demo pre-loaded. With TWO HalloWing boards and a few extra tidbits, it’s possible to make them work together as a pair of moving, blinking eyes.

Oh noes! An 11th-hour invite to a Halloween function and you don’t have a costume ready! Or maybe you want something discreet but fun when the work dress code doesn’t permit a full werewolf getup. HalloWing to the rescue! Our spooky little development board, plus a few extra tidbits from Adabox 009 (or your parts collection) can quickly make an eye-catching accessory that no good host would turn you away for being under-dressed. Some of these ideas require just a few minutes.
