Just like a TSOP IR receiver is a nice, neat, all-in-one solution that allows me to detect IR signals from a remote control, and pass them to a PIC for the software to actually decide what to do with it (on a falling-edge interrupt on pin A2)... is there a similar component / device used for detecting a sound... i.e. a clap or music or a voice?
In an ideal world, I guess I'd be looking at a single component - like a sensitive microphone - that, say, has three legs, one from +V, one to ground and one to an input pin of a PIC... but I have learned enough to realise that might not be possible. I'd be very happy with an IC solution too if one was available.
Maybe I would like more information from this device, like the frequency of the sound, so I could recognise differences that I would code for... but I'm not too sure yet... at the moment I'm just thinking about detecting either the presence or absence of sound (above a certain level (dB), of course... and I'm thinking this is why it might not be a single electronic component that does the job.
Any pointers greatly appreciated.
