I want to make a device to play a sound when a PIR sensor detects motion, but I don't know about the audio chip. I can't seem to find a chip that allows you to program a sound clip to it, then output it when it is given a signal. The closest I found was a cheap sound recorder module from china, but it contains all the external components (mic, batteries, speaker, switches) and so it acts just as a voice recorder. I need an individual chip that will do something similar. I may use the module as a prototype, but I eventually intend to mass produce the circuit, so that is why I am looking for an alternative. It only needs to hold about 5 seconds worth of audio, medium quality.
