Hello, I'm working on a color organ project and want to take a mic input (analog) get it's amplitude and frequency at any given moment, and send a signal to any one of 12 LEDs, each of which represent the 12 octave musical spectrum.
Here's where I'm at for the moment, while waiting for my Uno to show up.
This library : http://interface.khm.de/index.php/lab/experiments/arduino-frequency-counter-library/ has code I can understand to determine frequency.
But, it only senses on pin 5, which is a digital pin.
My mic BOB, will be connected to A0.
Now, if I understand things, if you use analog read, the onboard ADC converts it to digital. So, is there a way to send that to pin 5?
Or, would I have to connect the mic BOB to an ADC, which connects to pin 5?
Obviously, the latter solution would work, but wondering if I can use the software to get to pin 5, and simplify the hardware circuit.
TIA!
