Saturn V Diorama

A custom Lego Saturn V diorama build featuring lighting, fog, audio, motion and automated effects.

Overview

This project started as a Lego Saturn V display and evolved into a fully animated diorama with custom electronics and smart control. It combines lighting, fog, audio, motion and automation to turn a static display into a launch-themed showpiece. The core control is handled by Arduino, with Home Assistant and WLED used for triggering, sequencing and integration.

What It Does

Lighting Effects

Custom lighting throughout the diorama for launch ambience and sequence effects.

Fog / Mist

Atmospheric fog effects to help sell the launch pad scene.

Audio

Countdown and launch-themed sound playback tied into the build sequence.

Motion

Motorised movement to add life and mechanical action to the display.

Arduino Control

Main device logic for timing, outputs, sound and hardware coordination.

Home Assistant + WLED

Smart triggering, automation and addressable LED effects integration.
