I'd like to be able to detect a certian frequency using the Arduino. Anybody have an idea?
I'm brand new to the Arduino and I have the Duemilanove with the 328 processor.
The incoming signal will be a multitude of low frequencies, all of them less than 20Hz.. I'd like to be able to select one and turn on a digital output. I'll be able to take care of things like input amplitude and bias etc.
I would also like to find a good source for learning the programming language. Any help greatly appreciated.
