Dungeon 🆕

Description

The dungeon is the trap door to the haunted house's dungeon with zombie hands reaching up through the gaps. Eerie sounds can heard, occasionally a roar, red light and fog rises out of the cracks in the trap door. Oh, and there is an undead cat giving of terrible screeches.

The trap door is a wood pallet. There's a fog machine place underneath, red LED light, a speaker and there's an animatronics skeleton cat placed on top of the pallet.

In addition to the occasional roaring, the controlling RPi plays a continous loop of ambience sounds. This does not have to be enabled/disabled remotely - but it would be nice.

The LED light is always on (let's check that again).
