Common Christmas timber don’t emit gentle, nor do they react to music. If you would like each issues in a vacation ornament, think about this construct from [dbmaking].
An ESP32-D1 mini runs the present right here. It’s hooked as much as a strip of WS2812B addressable LEDs. The LED strip is positioned on a picket body resembling the form of a conventional Christmas tree. Ping-pong balls are then stacked contained in the picket body such that they act as a lightweight diffuser for the LEDs behind. The microcontroller can also be hooked as much as an INMP441 omnidirectional MEMS microphone module. This permits the ESP32 to detect sound and flash the LEDs in time, creating a colourful show that reacts to music. That is achieved by utilizing the WLED net installer to set the show up in a sound reactive mode.
It’s a enjoyable construct, and we’d like to tinker round with coding extra superior visualizer results for a construct like this. We’ve seen builds that go the opposite means, too, by firming down extreme blinkiness in Christmas decorations.
