This project is intended to be a solution for playing sound files and LED patterns using external triggers. I'm hoping to be able to make it small and cheap enough to permanently install in replica props, but also have all the functionality required on a single board. Products like this already exist, but this aims to be open source, friendly to build at home, and cost effective (fingers crossed). Additionally, I plan to have it so that changing patterns and sound effects does not require any firmware updates and is as simple as possible for those who may not be familiar with electronics.
