Pitch detector


Please bear with me I am a total noob with arduino.
I am looking for guidance regarding a pitch detection device.

I want to build a device which detects specific frequencies of an audio signal and lights an LED when the the right frequency has been detected. This LED-lighting frequency should be adjustable with an potentimeter.

Could this be realized with an arduino UNO?

Any help would be greatly appreciated!
