 Looking for a quick, no-soldering project for Halloween? Have no fear, this project gets you from zero to a flapping vampire bat in no time. You can build this animatronic bat with a circuit playground express and two servo motors. The servos have alligator clips that can clip to the circuit playground's pads. The bat's wings attach to the servo motors. Circuit Python code running on the circuit playground moves the servo motors in a flapping motion. The code also utilizes the LED animation library to animate the circuit playground's NeoPixels. To get flapping, power up the bat with either USB power or a JST battery pack.
