ExitLight - Arduino Emergency Exit Lighting & Path Illumination

About this project

Build standalone emergency exit lighting system using Arduino Uno with automatic battery backup for fire safety egress illumination. Detect power failure and automatically switch to battery power, illuminate exit path with high-brightness LEDs, monitor battery charge level, provide visual direction indicators, implement strobe mode for attention during emergencies. Perfect for stairwells, corridors, commercial buildings, and industrial facilities requiring code-compliant emergency lighting. Achieves 90+ minute runtime per NFPA 101 Life Safety Code with automatic testing and self-diagnostic features.
