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!
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
