Hi,
Apologies if this has been covered already but I am a complete newbie when it comes to arduino. Basically, I have the idea of making a map which has light sensors positioned under a selection of countries. When I hover my hand over a sensor I want it to trigger a particular wav file, either from a speaker or my laptop. How would I get this to work? I've looked into IR sensors but it looks like they may have too big a sensitivity radius. Obviously all the countries will be fairly close together and I don't want all the sounds to play at once.
All help is appreciated!
