Hi there people, a couple of guys in my college and I are planning to make this 'robot', which will dance to the music played to it. Basically, I'd thought of having the bot take in the sound input from a microphone, then amping it, passing it through a couple of filters for taking the bass and treble components from the music. The filter-output can then be passed to an Arduino uC in some form and thereon programming can take over.
I have a couple of doubts regarding this thingy:
First: what mic should I use for best results? Is using a normal music-player earphone backward as a mic sufficient? i read about electret mics.. is this the one I'd be needing?
And, wat filter design seems best? I guess active filters using op-amps would be the best bet, but I was told the 741 opamp is too noisy for this application.. suggestions?
Thanks in advance
