Let's say you have an LED display, and you want it to indicate volume from your TV, MP3 player, or other sound source. How do you make it work?
With Discover Audio with Arduino, you'll learn exactly that. You will build simple to intermediate volume unit (VU) meters using LEDs, analogmeters & circuits, LCDs, and the Arduino. You'll also build simple amplifier circuits to enhance monitoring sound of radios, TVs, and MP3 players. You'll even learn how to use the online simulation tool CircuitLab to analyze simple amplifier circuits for VU projects and experiments.
