Fully customizable audio-lighting effects for any kind of device that requires the emission of specific lights and sounds. In this project it has been realized for a self-built replica of a Star Wars weapon. The heart of the project is the Arduino microcontroller, which controls via 3 microswitch an RGB LED, 10 bars led and an MP3 player connected to 2 amplified speakers. Features: "shots" effects of different weapons; upgrade via SD card; audio amplified 3W; Led RGB 3W; LED bar for "ammunition status"; "reloading ammunition" effects; backgound sound effect "radio communications" activated by long press of microswitch; lithium battery (approximately 7 hours)
