I have a fairly complex project that is part mechanical, part electrical, part project management. One small section of that project is to play a simple .wav file in response to dry contact closure. This is in an industrial environment, so I need a device that can contain the .wav file, respond to the contact closure, and drive that .wav into something that can then drive a speaker. I can’t put a PC in location.
I haven’t done any electrical work since a good bit of relay logic circuitry in the early '90’s. This is a golden opportunity as my manager has given me the option of either buying it out (punt) or of learning/doing this myself. I’m opting for the learning/doing but I am the most beginning neophyte you can imagine. I asked around the net a bit and folks told me an Arduino board is the right tool for this job.
Is this the case? If so what other hardware besides the board would I need (either general device type or actual device recommendations appreciated).
I really do want to create this myself as a learning experience and skill builder rather than paying it out. OTOH, this has to be, at most, 24-36 hrs of work. I do have an electrical background, but not an electronic one. What do you suggest?
