When it comes to decoration for Halloween, or setting up an elaborate, Scooby Doo-esque plot to scare a bunch of meddling kids, it's hard to beat a creepy skull that looks at you out of one eye whenever it detects movement!
You can build this with the HalloWing and its TFT display, a lens, and a PIR sensor to determine when people are approaching, and then open up it's one good eye!
In addition to the parts listed above, you'll also need:
- Hollow plastic decorative skull
- Box cutter, hobby knife, or thin-bladed saw
- Hot glue and hot melt glue gun, or double stick foam tape
- Black felt or construction paper
