Sci-Fi Diorama with Sound and Lights

I'm creating a Sci-Fi model diorama and need a freelancer to help with the setup.

Essential requirements include:
- Integrating an Arduino system to trigger sounds and LED lights for military vehicles.
- Using pre-recorded sound files of tanks shooting and missile launchers at appropriate intervals.
- Setting up a continuous loop of sound until a momentary switch is pressed.
- Incorporating background sounds of troops firing different guns on repeat.

I already have a Mars War Machine which includes a sound module, so the task will primarily involve assisting with the Arduino setup and sound integration of above listed sounds and LED light triggers. Also suggest on what Arduino and compatible sound chip card to purchase.

Ideal skills for this project:
- Experience with model dioramas, especially in the Sci-Fi genre.
- Proficient in Arduino programming.
- Familiarity with sound and light integration in model setups.
- Creative problem-solving skills to ensure the sounds and lights sync perfectly.

I'm looking for someone who can help me bring this diorama to life!
