Arduino Shooting Target System

I'm looking for an experienced Arduino programmer to create a microcontroller-based shooting target system. The system will feature 20 targets spread over a wall, with individual LEDs that randomly light up and a sound effect when a target is hit.

Key Requirements:
- 20 targets with individual LEDs
- LEDs randomly lit
- Arduino-based microcontroller
- Sound effect on hit

Ideal Skills and Experience:
- Proficiency in Arduino programming
- Experience with individual LED control
- Knowledge of sound integration with microcontrollers
- Background in electronics and circuit design

Please provide relevant experience in your bids.
