Its a stack of LEDs that is a meter for the decible level of the music playing out of a laptop. the computer's audio output as an analog input signal to Arduino. The Arduino board then displays this as levels on a 10-LED display. I want to do something involving lights being activated by certain sound frequencies or decible levels.
