Hello, I am new to Arduino and i am looking to build a robot for my license project. I found an Arduino V3 board and I am not sure it could process fast fourier transform. My project is this: A robot listening and comparing samples to 5 presets, simply put, whistle patterns and then do something, like rotate for a few times. I need to know if Arduino's V3 16 mHz processor can do this in real time. Listening, comparing and executing if the compare is successful.
MSGEQ7 - Hmmm. I have a couple of those.. Pretty wide range of bands for whistle though. More designed for driving a "color organ" display from wideband music. I have a student who is working on a helmet with RGB LEDS - fibreoptics driven by Arduino and a MSGEQ7 .
Are there any other tuneable narrow band filters that are digitally controllable??
