I don’t know if this is the right place to do this, but I have a project and I need a speaker compatible with an Arduino red board that I can pre upload sound to. I don’t know if this is a product that exists but the idea is when something is within a certain distance of a sensor the speaker will play an audio file
You’re not going to find a speaker you can upload sounds too, but you might be able to connect a [wav trigger to a speaker and do what you want that way. :-)](https://www.sparkfun.com/products/13660)
