The Adafruit Prop-Maker Starter Kit contains the electronics you need to build a 3D-printed NeoPixel lightsaber with motion-activated lighting and full sound effects. The kit pairs the Feather M4 Express with the Prop-Maker FeatherWing, giving you an accelerometer for swing and hit detection, a Class D amplifier for sound, and high-current NeoPixel driving — all in a compact, battery-powered package.

The on-board LIS3DH accelerometer detects swings and impacts to trigger super-bright NeoPixel animations and sound effects in real time. Programme it with CircuitPython for easy customisation of colours, animations, and audio clips.
