If Halloween has snuck up on you, have no fear! This project gets you from zero to flapping vampire bat with no soldering required. You'll use a Circuit Playground Express, two servo motors and CircuitPython to build this fun Halloween prop.

The bat's wings are mounted to two servo motors that move up and down to create a flapping effect. The servo motors have alligator clips that attach to the pads on the Circuit Playground Express.

The NeoPixels on the Circuit Playground Express animate with a swirly comet pattern.
