More and more Arduino and Raspberry Pi are used in theatrical productions. There’s always been an affinity between Makres and theater technicians. In both cases the ethic is that whatever the problem is, you can find a solution for it on your own terms.
You are more likely today to play a sound effect off of digital media and through speakers, and less likely to make use of the storehouse of theater tradition with its crash boxes, starter pistols, thunder runs and, yes, phone ringers…making a phone ring is an instructive problem. One word used around the Arduino community is “Physical Computing.” Or, as Tom Igoe puts it, “Making Things Talk.” And that is the problem of getting software in the virtual world to do something out here in meatspace.
