The Adafruit HalloWing board ships with a spooky eyeball demo pre-installed by default. But what if you want two eyeballs peeking around?

Some prior projects have you soldering up two graphic displays and either a microcontroller or Raspberry Pi…but neither was “HalloWing simple.”

Now we’ve cooked up a way for two HalloWing eyes to sync up and move together…and it requires no soldering at all! And with our ready-made designs, you might not even need to touch a code editor.

The eyes are great for things like Halloween, as part of a jack-o’-lantern or a window decoration (we even have some templates you can print and use)…or for cosplay, where they might go on a hat or be part of a companion prop.
