Whether it's crawling across the floor, popping out of a grave, or snapping its fingers to a catchy tune, the disembodied hand is a scary movie staple. It's also the perfect prop for your Halloween display -- especially when you add flashing lights and eerie music!
This version is quick to make and easy enough for kids to do themselves (or with a little adult help). The hand itself is made completely of masking tape. Inside is a circuit made with peel-and-stick fabric conductive tape. The lights in the fingers are Adafruit LED Sequins, but you could even use ordinary LEDs. And the palm lights and the coding are all done in simple to use, block-based Microsoft MakeCode on the Adafruit Circuit Playground Express (CPX for short).
Feeling fancy? Instead of Sequins, this guide also shows you a solder-free way to attach an Adafruit NeoPixel LED Dots Strand, and run pre-made animations or control each individual color-changing light with MakeCode.
Ready to pay a call on this disembodied hand? Let's get started!
The Circuit Playground Express lets you create your own light sequence and add music to your creepy, kooky creation! You will need one for both versions of this project. The base kit also includes a USB cable for programming the board, plus batteries and a battery holder to make the project portable.
Here is what you'll need to make the version using non-programmable LEDs.
Or, to make the version with programmable lights throughout, this is what to get:
For both versions of this project you will need scissors.
For the NeoPixel LED Dots Strand version you will also need:
- small Phillips head screwdriver
- wire stripper, like the one below
Other supplies you will need are:
- masking tape
- cardstock or other heavy paper
- disposible straw, tongue depressor, or stiff paper rolled up into a straw-shaped tube
