I would like to know if it is possible to write a program for arduino where a tune is played through a speaker/pitch sensor and LEDs flash. What I would like to know is: is it possible to code it so that when the tone goes higher the next LED lights up and when the tone goes lower the previous LED lights up?

Thanks for any help, M
