I got an interaction design project for my MFA and i would like to build a fairly simple circuit for it: a sensor with two parts - when they are aligned a relay or a switch of some sort goes to high and triggers sound playback. I have a bunch of questions, mostly about what parts i should use: what should i use for the sensor, for the brain and where should play the sound from - would a CD walkman work or can i get a raw sound storage and playback circuit, the kind they use inside some teddy bears?
Any and all ideas are welcome and appreciated.
Thanks in advance.
